1. Colour physics, dispersion of sunlight into colours of the spectrum. (Sir Isaac Newton 1676) Discuss and illustrate Newton’s experiments and beyond, from particle to wave theory.
2. Research, identify and illustrate how the eye sees colour, reference to light emitted, transmitted and reflected.

1. Sir Isaac Newton, held the theory that light was made up of tiny particles. Around the same period, Christiaan Huygens, believed that light was made up of waves vibrating up and down perpendicular to the direction that the light travels. Huygens theory was the successful theory of light wave motion in three dimensions. Huygen suggested that light waves peak form surfaces like the layers of an onion. In a vacuum, or other uniform medium, the light waves are spherical, and these wave surfaces advance or spread out as they travel at the speed of light. This theory explains why light shining through a pin hole or slit will spread out rather than going in a straight line.

At the time, some of the experiments conducted on light theory, both the wave theory and particle theory, had some unexplained phenomenon, Newton could not explain the phenomenon of light interference, this forced Newton's particle theory in favor of the wave theory. This difficulty was due to the unexplained phenomenon of light Polerisation - scientists were familiar with the fact that wave motion was parallel to the direction o...

    Another speaker, Margaret Livingstone delves into the visual aspect of our senses. Livingstone mentions how artists recognize things about vision that neuroscientists are not privy to until years later. Livingstone discussed the differentiation between color and lightness, and how the two contribute differently to a work of art. Color is thought of as “comparing activity” whereas light is thought of as “summing them.” Livingstone indicates that the visual system is subdivided into a ventral system and a dorsal system.

  • The Color-In-Context Theory: The Romantic Red Effect

    513 Words  | 2 Pages

    The pupil is where light can enter the eye. The iris is in control of the amount of light that actually goes through. The light reaches the lens, which alters the shape of it so the eye can focus on it. Light reaches the retina, which consists of cones and rods. Colors are saw differently based on their implied meanings, which to various psychological functions. The cones are responsible for color. The color red would have such an effect on people’s perception of others based on their production of affect, behavior and cognition. A sociocultural theorist would explain this effect by indicating that the associations with the color red are normal. When a student sees a plethora of red marks on their paper, they automatically think they failed the assignment. Biological theorist would best explain this theory by saying the color red helps them survive or reproduce. A man may be attracted to a woman more because she is wearing red. This attractiveness could cause him to find his mate and eventually reproduce. A behavioral theorist would explain this effect by saying the color red provokes pleasure and avoids pain. A person can associate red with romance and

  • On the Quantum Mechanics of the Human Intellect and the Stories It Creates

    2918 Words  | 6 Pages

    During the crisis of modern science in the late nineteenth and early twentieth centuries, the postulates of early scientific discoveries had been refuted. In one of science’s most defining moments, an undisturbed photon of light was found to exhibit both wave-like and particulate qualities. The relationship between these two qualities would later be termed complementarity by Niels Bohr, one of the scientists at the forefront of this discovery. As Thomas S. Kuhn notes in The Structure of Scientific Revolutions, “Before [the theory of quantum mechanics] was developed by Plank, Einstein, and others early in [the twentieth] century, physics texts taught that light was transverse wave motion” (12). So staggering was this discovery that in his autobiography, Albert Einstein recounts, “All my attempts to adapt the theoretical foundations of physics [to the new quantum knowns] failed completely. It was as if the ground had been pulled out from under one, with no firm foundation to be seen anywhere upon which one could have been built.” Not surprisingly, this arrest of the fundamental postulates of classical physics sparked a reevaluation of the “world view” by the ...

    In 1896, in Plessy v. Ferguson, the Supreme Court ruled that separate but equal accommodations for blacks and whites were constitutional. Seven years before the doctrine was overturned, in 1954, Jackie Robinson signed a contract with the major leagues; he defined his experience as being “a black man in a white world” (279). With the separate but equal doctrine still in place, how was Jackie Robinson able to land a contract with the major leagues, and what role did he play in the Civil Rights Movement?

  • Hook Sentence: Should Books Be Banned

    488 Words  | 1 Pages

    People ban books for dumb reasons that make absolutely no sense. Another is dumb religious reasons. Ministers and educators challenged it (it being the wonderful wizard of oz) for its “ungodly” influence and for depicting women in strong leadership roles They banned the wizard of oz because it showed girls in a leadership role (what?).This is really important because they are banning a classic book because the princess was a thing that people got really people got upset with it. “Others accuse the novel of attacks on religion, the disabled and women.” Lord of the flies (“http://www.banned-books.org.uk/sections/corrosive”). Once again PC police have come again to shut down another book that is actually pretty good.Also once again imagination is not encouraged. Don’t ban books for religious reasons that are not valid. Finally racism (that is not racism). “"A review of the book in question shows it to include pervasive vulgarity and racially insensitive language,"(The Hate you Give) Hindt said.” The story is about the struggles of a black girl in a racist environment (wouldn’t this be considered anti-racist). They can basically just ban whatever book they want.The Adventures of Huckleberry Finn by Mark

  • Spectroscopy

    However Spectroscopy is not a recent development, as it has been utilized for many years since Isaac Newton made the first advances in 1666. Spectroscopy is the study of light as a function of wavelength that has been emitted, reflected or scattered from a solid, liquid, or gas. Fundamentals of Spectroscopy Spectroscopy is the distribution of electromagnetic energy as a function of wavelength. Spectrum is basically white light dispersed by a prism to produce a rainbow of colours; the rainbow is the spectrum of sunlight refracted through raindrops. All objects with temperatures above absolute zero emit electromagnetic radiation by virtue of their warmth alone; this radiation is emitted at increasingly shorter wavelengths as temperature is increased.

    During the seventeenth century, the modern science of physics started to emerge and become a widespread tool used around the world. Many prominent people contributed to the build up of this fascinating field and managed to generally define it as the science of matter and energy and their interactions. However, as we know, physics is much more than that. It explains the world around us in every form imaginable. The study of physics is a fundamental science that helps the advancing knowledge of the natural world, technology and aids in the other sciences and in our economy. Without the field of physics, the world today would be a complete mystery, everything would be different because of the significance physics has on our life as individuals and as a society.

  • The Double Slit Interference And Davisson-Germer Experiment

    954 Words  | 2 Pages

    In 1801 Thomas Young provided some very strong evidence to support the wave nature of light, he placed a monochromatic light in front of a screen with two slits cut into it, and observed an interference pattern, only possible if light was a wave. In 1965 Richard Feynman came up with a thought-experiment that was similar to Young’s experiment. In Feynman’s double-slit experiment, a chosen material is fired at a wall which has two small slits that can be opened and closed at will – some of the material gets blocked and some passes through the slits, depending on which ones are open.

  • Special and General Relativity Essay

    797 Words  | 2 Pages

    Einstein's theory of relativity is a famous theory, but it's little understood. Essentially, the theory of relativity refers to two different parts of the same theory: special relativity and general relativity. The theory of special relativity was introduced first, and was later considered to be a special case of the more comprehensive theory of general relativity. During the nineteenth century, scientists believed that light is a wave. They reasoned that waves of light need a medium to travel through, so they invented the concept of "ether." Light was thought to transmit through the ether, which stands still while all matter moves through it. In order to measure the earth's speed through the ether, Albert A. Michelson and Edward Morley collaborated on an experiment in 1887. In the experiment, one beam of light took a route against the ether and back while the other was perpendicular to the ether. Michelson and Morley expected to calculate the speed of the earth through the ether, to their surprise, the beams of light completed the course in the same time. However, the well-known Michelson-Morley experiment had failed to detect Earth's motion relative to the ether and no one could explain why. Something was wrong with the traditional understanding of relativity as it applied to light. Within this essay we will further explain both parts of the theory of relativity and their relevance in our world.
