Sir Isaac Newtonaccomplished many things. We have learned quite a lot from what he hasdiscovered, and most of it’s used in today’s education systems. Most of us havebecome familiar with his three laws of motion and have applied them to dailylife. Aside from that, one of his most important accomplishments also includesinventing the Reflecting Telescope. Galileo Galilei was one of the first peopleto invent a telescope, but this one was invented in 1668. The main purpose ofthe Reflecting Telescope is to be able to see the visible region of theelectromagnetic spectrum.

Because of this invention, we have discovered how theconcept of reflection affects the different aspects of life in depth.               In U.S. history, two main types oftelescopes have been discovered. While the refracting telescope focuses onlight using two lenses, the reflecting telescope focuses on light using twomirrors.

The main purpose of telescopes is to try and focus on certain objects,shapes; colors. Without telescopes, we wouldn’t have the chance to explore theuniverse, or find a simple explanation as to how our mother nature works. Thevery first invention of telescopes date back to the late 1500s because to thisday, the inventor of the telescope is still unknown. But even if that’s adisadvantage, astronomers still specify that the telescope is one of”humankind’s most important inventions”.                         There are three main parts of atelescope. Mainly, telescopes have lenses, mirrors and an eye piece. Theeyepiece is somewhat part of a lens because the other type of lens is called anobjective lens. The objective lens is perpendicular to the eyepiece as it’spointed directly to the object that someone or something is looking at.

Themain purpose of a mirror inside of a telescope is to reflect or refract lightrays while someone or something is looking through the eyepiece.             Theories were gathered and most ofthem repeatedly said that anyone with two lenses could have figured out whatbig advantages it could bring to build up curiosity of the outside world. It issaid that the very first telescope was made because of interest in a weathervane. In other words, the earliest scientists were curious about whatdirections was the wind coming from, and could they somehow see it from afar. Specifically,Galileo Galilei was in the mindset that the sun was the center of the universe;that all the planets revolved around the Sun. So, he set out to inventsomething that would let us see into space.

Although he isn’t the initialinventor of the telescope, we can say that he helped evolve our curiosity onwhether he was right about his theory. A couple years later, Sir Isaac Newtoncontinued the work of the newest telescope.             In 1668, England, Newton inventedwhat was called a Reflecting Telescope and established a patent. For manyyears, scientists have struggled to find something that would help see imagesmore clearly without having a problem of only seeing a couple of colors at onetime.

These scientists wanted to find a way in which all colors in theelectromagnetic spectrum would be visible. The tool that they had created had alens that had light pass through it in order to see the numerous colors. Theonly problem was that the outcome wasn’t as expected. Newton, on the otherhand, figured out what the problem was and fixed it plain and simple. He tookthe lens out and replaced it with a mirror which would be later called as a concavemirror.

With this concave mirror, the light would be reflected, therefore wecan see all the colors, but there would still be some blurry images.             The mirror that was in place of thepiece of glass had a curved shape to it. As images got closer to the mirror, theywill be inverted.

In order for an image to reflect, the mirror must have thephysical support. The mirror’s front space was covered in aluminum for a highlyreflected image and the back space was covered in glass. Just because thealuminum is placed in front of this primary mirror, doesn’t mean that thetelescope will produce a perfect image. Telescopes have their fair share oferrors as well. Because of the primary mirror that is placed inside the tube ofa telescope, the only error that would be mostly produced is sphericalaberration.

In other words, there wouldn’t be a perfect image. There would be asomewhat blurry image, but not to the point where you can’t see the image atall.             As we now know, the primary mirroris the most important aspect of a Reflecting Telescope. This primary mirrorwill focus onto the center of the tube. On the other hand, there will be asecondary mirror placed inside the tube to focus on the sides of the telescope.The point where this light is reflecting in the telescope is about where thelight actually hits the mirrors. As we look through the eye piece, light willhit the primary mirror, reflect off of the secondary mirror and its path willgo straight to the eye piece. When the light reaches the eye piece, we wouldautomatically be able to see the images formed through this telescope.

            What holds the primary and secondarymirror together is called a Tube Assembly. This is just like a strong supportto hold the telescope together. The other main parts of a Reflecting Telescopeare called a counterweight and a motor. A counterweight is a small black knob,that you would normally see on every telescope. It is used to balance an imageand see whether it is clear enough, or if you should adjust it. The motorallows you to point the telescope directly at what you’re looking at andfollows it through and through until to the point where you are done with thatresearch. Lastly, the unique part of a reflective telescope is called afinderscope. While the word might be self-explanatory, the finderscopebasically finds the object that you are looking for in the reflectivetelescope.

            In today’s society, ReflectingTelescopes are used in astronomy. Like we see the colors of the electromagneticspectrum form into the sky after a rainy day, this tool is used to see manyunique images in the sky. In daily life, we see the process of ReflectingTelescopes. For example, the primary mirrors that are used in these telescopesare what we use in stores at self-checkouts.

In this case, the light thatreflects is a laser that is used to scan bar codes when we purchase certainitems. While these lasers don’t cause damage to our peripheral vision like mostlight sources do when reflected, they make the supermarket shopping much moreefficient for all customers. Also, while light may contain differentwavelengths or different colors, lasers are the type of light that only containone type of wavelength. In other words, it mostly only contains one color. Ingrocery stores, we see that the light that comes out for these self-checkoutsare usually red in color although the laser comes out split due to thereflective mirror that is placed inside.             The science behind the reflection ofa mirror is that it there is an incident ray and a reflected ray. The reflectedray will have the same angle of reflection as the incident ray as light bouncesoff the mirror.

An example that describes the two different angles is a sunset.The angle of incidence bounces off the primary mirror. In this situation, it’s thewater, and the angle of reflection is the same as the angle of incidence as it bouncesoff the water. That’s why we can see the reflection of light from the sunset rightside up in the distance and up-side down in the water.            Reflective Telescopes come from afoundation of reflection. The main basis of reflection in everyday life is lookinginto a mirror.  As someone who looks intothe mirror every day, looking at my reflection is part of my daily routine. Likethe primary mirror inside of a reflecting telescope, this main mirror is theprimary mirror that we look into.

  Whenyou place a smaller mirror, say a make-up mirror, in front of a larger mirror,it’s the same deal as looking into a reflective telescope. That way, both theprimary and secondary reflect light in order to form the images that we arelooking for. In this case, the resulting image would be ourselves.

Concavemirrors are mostly used for the make-up mirrors, and most importantly, concavemirrors are used in this telescope. Without these concave mirrors, we wouldn’tbe able to see the virtual image of ourselves. Concave mirrors can make real images,but it depends on the distance that we are standing from the mirror.             In other words, when we switch on thelight in the bathroom, the light comes from an angle from the one side and bouncesoff the mirror to which the reflecting angle produces the same degree and spreadsinto the opposite direction. This is why we are able to see ourselves through aone-sided mirror, and this image that it produces is called a virtual image. So,the mirror is actually halfway between us and the virtual image that the mirrorgives us.             It’s because of the invention of theReflective Telescope, that we can experience the science behind it in oureveryday lives.

Even the littlest situation that happens in your life pertainsto physics. Looking through a window, and looking through a magnifying glass islike looking through a lens of a telescope. At the same time, looking at amake-up mirror or looking at the normal flat mirror in the bathroom, is likelooking at the primary mirror through the eye piece.             The science behind ReflectiveTelescopes are also defined when x-rays are used in hospitals. As said before,reflective telescopes collect all the light at one point, so the light isvisible at one point. The same concept is used in x-rays. Reflection isn’t ashigh as what’s in the telescopes, but they have little reflection.

X-Rays arefully reflected when used in Computed Tomography scans; also known as CT scans.The purpose of CT scan is to get a full x-ray view of the problem that isassociated with your body. During a CT scan, x-ray tubes rotate around causingan x-ray vision of your body. Therefore, it produces a clear, but imperfectimage. The reason for a clear image is because x-rays are not directly focusedin you. Instead it’s focused at an angle because light always hits the mirrorat a certain angle in order to produce a non-blurry image.

If you aren’t lyingstill on the table, it might produce a blurry image.              Reflective Telescopes have nowbecome an invention of a lifetime. The more we heighten our curiosity, the morewe want to discover for ourselves or for our society. The reflective telescopehas evolved over the years, and we still use it to this day to thoroughlyexperience the impact it has on today’s society. Not only have reflectivetelescopes impacted us, but just telescopes in general as well. Now, we areable to see more than what we couldn’t have been able to see back in the late1600’s when it was first invented.             Over the years, science is taken forgranted and has developed a lot of pros for society.

Now we can use thistelescope in a more comfortable working space than back then. Our thoughtprocesses have accelerated to what we can do more for science itself. It’sbecause of these inventions that we can think about what more can be done toimprove what has already been invented for it to be people friendly. If itweren’t for Sir Isaac Newton, or Galileo Galilei, we wouldn’t have even thoughtabout making something that would change the rest of our lives.              Without the telescope, we couldn’thave figured out the science behind ROY G BIV, or any other color for thatmatter. There are lots of questions that have been answered, and questions thatare yet to be answered in the real world.

For example, why is Red a bettercolor than Blue for a laser when you are checking out groceries? Or, why do we usemirrors in order to see a better perspective of our reflection? Or, why do CTscans always have to be done at angle, why can’t they just reflect lightstraight down the human body? Although, it’s very difficult to reflect light usingthese CT scans, it’s still done to create X-Rays in today’s hospitals. Bluelasers are ineffective because it causes way more damage to the vision than Redlasers. Green lasers aren’t used because they are way brighter than Red lasers,and customers don’t need the trouble of managing them just for the shopping.

            The more answers we get, the moretheories we make, the more conclusions that are the truth, or sometimes false,the more questions we must ask again in order to clear suspicion or doubt.Without science, there is no way people would be able to understand fact versusopinion.
