colour physics Essay - 701 Words

Colour Physics 712 words 1.nbsp;nbsp;nbsp;nbsp;nbsp;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.nbsp;nbsp;nbsp;nbsp;nbsp;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†¦show more content†¦Eventually the two wave fronts will overlap with each other, if a screen was placed at the point of the overlapping waves, you would see the production of light and dark areas. One bright afternoon, Newton darkened his room and made a hole in his window shutter, allowing just one beam of sunlight to enter the room. He then took a glass prism and placed it in the sunbeam. The result was a spectacular multi-coloured band of light just like a rainbow. The multi-coloured band of light we now know as the ‘colour spectrum’. Newton believed that all the colours he saw were in the sunlight shining into his room. He thought he then should be able to combine the colours of the spectrum and make the light return to it’s original state (white light). To test this, he placed another prism upside-down in front of the first prism. He was right. The band of colours combined again into white sunlight. Newton was the first to prove that white light is made up of all the colours that we can see. 2. The human eye is the final link in the chain of colour vision. The human eye has a basic two element lens. The cornea is the front or outer element and the lens is the back or inner element. The amount of light entering the eye is controlled by the iris which lies in between the two. The lightShow MoreRelatedThe, Peace, Night, Day, Love, Hate1946 Words   |  8 Pagesdifferences between these pairs, it fails to entertain an idea even more compelling; that these polar opposites may not in fact be that different from one another, and the bold notion that these dichotomies might not be as real as we presume. Art and physics have been traditionally painted as polar opposites; neither resembling the other even remotely. One is rational, objective, and logical, while the other is interpretive, subjective, and, at times, seemingly illogical. While these superficial characteristicsRead MoreJacques Maritain s Philosophy Of Nature Essay1837 Words   |  8 Pagesthree degrees of abstractiv e visualization. At the first degree we have â€Å"being as subject to change† (Maritain 13). The mind abstracts from singular sensible matter, matter that is changeable, and leaving behind certain aspects like its location, colour, and size to know what it is. For example, looking upon a tree, the mind leaves behind its whereabouts and wants to get at what it is – namely, treeness. At the second level of abstraction, the mind knows being as quantity or mathematical knowledgeRead MorePhysics Of String Theory Of Physics1543 Words   |  7 Pagesnumber of excitation modes - that are the elementary particles observed. the strings have tension of 1/(2 p a’) strings are approximately the planck length (smallest possible size of black hole) 10^(-33) cm A quantum Theory of Gravity is needed In physics there are two main central theories. The first is Einstein’s theories of relativity. The second is quantum mechanics. Einstein’s theories of relativity describe gravity but does not include quantum effects. Quantum mechanics describes the universeRead MoreNuclear Physics Of The Society Development1374 Words   |  6 PagesNuclear physics in the society development Nuclear physics is the field of physics that studies atomic nuclei and their constituents and interactions. The most commonly known application of nuclear physics is nuclear power generation, but the research has led to applications in many fields, including nuclear medicine and magnetic resonance imaging, nuclear weapons, ion implantation in materials engineering, and radiocarbon dating in geology and archaeology. Nuclear physics has a lot of importanceRead MoreGauge Bosons : Fundamental Interactions And Their Evolution2354 Words   |  10 PagesGauge Bosons: Fundamental Interactions And Their Evolution Ray Sahab, Harpreet Kaur, Manish Rawat, Kanishka Kumar Singh Department of Physics, Indian Institute of Technology, Roorkee – 247667 Abstract In this paper, we study the four fundamental interactions, namely electromagnetic, weak, strong, and gravity separately along with its corresponding gauge boson; the theories of the four fundamental interactions and their evolution was studied carefully. We constrain ourselves to study the onlyRead MoreTaking a Look at Quantum Dots1836 Words   |  7 PagesTo begin with in layman’s language or maybe for a person who has limited or little knowledge about physics, quantum dots are materials that are small but are sufficient to exhibit quantum mechanical properties. Quantum dots were first discovered in 1980. They exhibit electronic properties which are between semiconductors and discrete molecules. That is the very reason for the unusually high surface to volume ratio. The most visible use of quantum dots is in fluorescence where the nanocrystal is capableRead MoreColour Ontology is Philosophy that Interacts with Nature633 Words   |  3 PagesWhile the word colour in the 7th Edition of Oxford Advanced Learner’s Dictionary is defined as: â€Å"The appearance that things have that results from the way in which they reflect light.† Colour can be identified by two different methods which are objectively and subjectively. The terms objectively in colour ontology is a method that using the facts by referring to the laws of physics, chemistry and physiology. Subjectively is the term that referred to the psychological concept. The colour ontology orRead MoreDefine Creatio Ex Nihilo1625 Words   |  7 Pagesa while. For example: Blue is a colour, as are yellow and red. All three of these colours make up every colour tone we see. Theoretically, there was an absence of colour, what would be in its place, white or black? It is very difficult to imagine this, as all our life we have been able to distinguish what we have seen because of their colour(s). Even when we try to imagine a world without colours, it becomes impossible not to end up labelling the absence of colour either â€Å"blackness† or â€Å"whitenessRead MoreEssay On Physics Of Complex Systems722 Words   |  3 Pagesand fascinating research areas in physics nowadays is the physics of complex systems, or the theory of complexity. There is not a single and straightforward meaning associated with this buzzword due to its vagueness and polysemy, and very often it depends on the context and the authors. Nevertheless, one of the interesting points are the tools and methods that the theory provides that can be eventually applied to many different disciplines, ranging from physics, chemistry, biology, applied sciencesRead MoreEssay on The Problem of Knowledge Due to Language1085 Words   |  5 Pages means ‘substancesÂ’.

What makes Natural Science different from other areas of knowledge is that we gain knowledge by using ‘scientific methodÂ’ which made up of observation, reason
