Colour Physics
712 words
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 of wave travel, not perpendicular to the to the direction of wave travel as light is.
In 1803, Thomas Young studied the interference of light waves by shining light through a screen with two slits equally separated, the light emerging from the two slits, spread out according to Huygen's principle. 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...
