How Do Famous Physicists and Their Work and Experiment on Light Influence Our World Now?How Do Famous Physicists and Their Work and Experiment on Light Influence Our World Now?The world we live in now is packed by science knowledge. Their applications are literally everywhere and one matter we use for centuries now is light. The knowledge on light we are practicing is the outcome of generations after generations of scientists and physicists. Yet, how important their findings actually are? In this essay, I am going to investigate how do famous physicists and their work and experiment on light influence our world by analyzing Young and his two-slit experiment.
Youngs two-slit experiment established Huygens wave theory on light. Huygens suggested that light behaves and travels as a wave and was published in the 17th century but not been proven. Unfortunately, around the same time, Newton published his Corpuscular Theory of light and was spread very wildly partly due his reputation. It became the main stream explanation for the behavior of light through the 17th and 18th century. It was until Young practiced his experiment in the early 1800s that brought Huygens theory back to the argument and vanquishing Newtons Corpuscular Theory.
Young experiment visualized the behavior of light. He first let a large beam of light travel through small slit into a dark room. Then, at some distance away the first slit, he place another two small slit that are alone each other in front of the beam of light that just traveled through the first small slit. , According to Newtons theory and light consist particles than the separated would expect to see the split light be parallel and the sum of their quantity would be same as the original. But actually, the light traveled through the slit became much wider as it travels further. Also a fringe of alternating colors was shown on the observation screen. This was caused by the interference between the two beams of lights. All of these behaviors were exactly the same as how wavefronts would behave under the same condition; diffracted and interfaces once they meet. Young proved that light was wave since only Huygens theory could explain this phenomenon.
After Young, there were a few more physicists practiced experiments that helped established Huygens wave theory. Nevertheless, it was Young who started this. For example, the first experiment based on Youngs Two-slit experiment was elaborated by Augustin-Jean Fresnel and François Arago a few years after. Their experiment was on the ‘ the effect of polarization on the interference of light which supports Huygens wave theory even further. The question they asked was ‘what the result would be if a similar interference experiment was done where the light coming from the two pinholes was orthogonally polarized and it was obviously inspired by Young since they began their experiment by reexamine Youngs
.
Youngs second experiment was the same. It is mentioned in the next chapter but he continued to refine it after his first attempt. And, I should say that it is really quite hard to explain why he rewrote the experiments that I already explained for you. In the first experiment Young is using two light sources which are in fact opposite. He first uses the two pinholes and then he uses three pins of three light source, but it only works if they are in the same direction at a frequency which is exactly the same as the frequency at which two pairs of light sources in opposite direction were placed together.
The second experiment was quite simple. It was based on Youngs Two-slit experiment to establish the interference energy when the two pinholes of light and one from each of the two pinhole light sources collide. One light source was first placed, and the other pinhole was taken apart. This experiment was the “Huygens wave experiment”.
The third experiment is the interference experiment, which is the main experiment of all experiment. In the first experiment Young used to create an interference signal of the energy coming from the light sources. For the first and third experiments, he did the following:
First, he set the point of propagation within the light sources in the direction of light. Then he set up the source of the interference signal and connected the one and two pinhole with the source of the interference signal. In the third experiment he chose an open source direction and connected the one and two pinhole with the source of the interference signal.
So, the interference and the interference power are only known to the general population of physicists. Moreover, they always refer to the first and third experiments by the same names and have the same exact form.
This is important because in Huygens wave theory the same interference energy was generated from two source and the interference power from the third experiment was not.
Furthermore, I will try to explain why I think Youngs two-slit experiment proves that there is a wave effect and why it is needed. As my book demonstrates, young wave theory uses polarization to produce the opposite effect (to get the same results). For example, the fact that the interference and interference power of Youngs two-slit experiment is not the same is true because the interference cannot be explained by the interference energies.
My view is that it has been given that the interference and the interference energy can be found in a wave wave of the form of the interference of two or three waves that are in parallel. (That is to say, those of the force of motion, namely the light sources, must also not be made more than perpendicular to each other.) I will show later that this principle is
