Light Essay

Providing the basis of nineteenth century physics, Young's Double Slit Experiment proved that light was made up of waves. During Thomas Young’s time, it was very difficult to describe the behavior of light. The predominant theory was that light was made up of particles. However, in his experiment, Young was able to observe the interaction of light waves when passed through two slits, showing the wave-like nature of light. This report will cover the reasons for Young’s experiment, the experiment itself, and its implications.

Light is a photon , which are tiny particles of light, however photons have electrons and protons which behave like waves and particles based on their given charge, this is the wave-particle duality. There is no clear distinction. When light behaves like a wave it responds to a particles electron frequency. When discussing frequency we are referring to light 's wavelength which is based on light 's energy.When the frequency

During the centuries preceding Young's experiment, light was widely accepted as being comprised particles, not waves. This theory was made popular by Sir Isaac Newton, and accepted as true until Young proved him wrong in 1801. Young sought out to prove that light was made of waves, not particles; but his findings opened up a whole new spectrum that scientist never foresaw.

Sir Isaac Newton held the theory that light was made up of tiny particles. Before, most theories of light had an unexplainable phenomenon. Einstein had suggested that tiny particles which have energy, called protons, formes into light. This suggestion was made when he proposed a solution to the problems of observations discovered on the actions of light having the characteristics of both wave and particle theory.

For instance, throughout the nineteenth century, it was correctly believed that light was a wave. If light were a wave like all other waves, it must have a medium through which to propagate through. This medium was called the ether, a substance which was everywhere throughout the universe. If this hypothesis were true one would be able to calculate the velocity of the Earth through the ether. Many experiments were conducted to determine this velocity the most famous one being the Michelson-Morley experiment.

Modern science is based on material, experimental evidence, but if matter is non-material as the physicist's fundamental forces suggest, then it will not be able to explain what matter is. It can only explain how nature works by observing the effects on material objects. In his book In Search of Schrödinger's Cat ch. 8, Gribbin suggests the possibility that no particle is real until it is observed. The act of observation collapses the wave function so that one of a number of ghost particles becomes a real particle. This idea has similarities with idealism and its appearance and reality arguments. Gribbin does not take the argument forward so let us consider the philosophical arguments instead of the physics.

Dating back at the time of World War II, Art Spiegelman's Maus recount the story of Vladek Spiegelman's life as one of the survivors of holocaust and the pain of his struggle to stand during those dark ages. Likewise, Thanhha Lai's Inside Out and Back Again also recite the effort and agony that a Vietnamese family had to go through during the Vietnam War, how they strive to survive and how they adapt as the refugees of the war. It can be found that Art Spiegelman's book, Maus and Thanhha Lai's book, Inside Out and Back Again show prominent influences of both kindness and prejudice towards the creation and the growth of the characters in the books. In these books, kindness and prejudice are depicted as essential features in humans' lives, both explore the different sides of helpfulness and prejudgement. The books portray that people's prepossession or prejudice is indeed a substantial necessity for people to avoid dangerous situation and probably understand one another and themselves better. Similarly, hospitality and kindness that are shown in both books depicted differently by twisting from the assumption that helpfulness is commendable deed to kindness is driven by agonising ulterior motives. Both books reflect the excruciating truth behind humans' kindness and the unseen assistance of hunams' prejudice.

Ever since 1867, immigration has been essential to the growth of Canada. With a larger population the land can more effectively be used and will directly benefit the economy. In 1912 Canada was distributing land to foreigners for cheap prices hoping that the economy would take off. Sydney Morgan and Emma Morgan, my great grandparents, were some of the people who purchased land in the prairies of Saskatchewan. Immigrating as a Welsh person generally put people at an advantage when facing immigration policies

Part I: The Edge of Knowledge Chapter 1: Tied Up with Strings This is the introductory section, where the author, Brian Greene, examines the fundamentals of what is currently proven to be true by experimentation in the realm of modern physics. Green goes on to talk more about "The Basic Idea" of string theory. He describes how physicists are aspiring to reach the Theory of Everything, or T.O.E. Some suspect when string theory is completely understood that it might turn out to become the T.O.E.Part II: The Dilemma of Space, Time, and Quanta Chapter 2: Space, Time, and the Eye of the Beholder In the chapter, Greene describes how Albert Einstein solved the paradox about light. In the mid-1800's James Maxwell succeeded in showing that light was actually an electromagnetic wave.

The Causes of Domestic Violence Domestic violence should not happen to anyone. It does and when it does , look for help. It may be happening to you or someone you know. I believe, domestic violence is caused by psychological factors as abuse, emotional abuse, and the need for one’s partner to dominate and control the other.
