WebTheories of light. In the seventeenth century two rival theories of the nature of light were proposed, the wave theory and the corpuscular theory. The Dutch astronomer Huygens (1629-1695) proposed a wave theory of light. He believed that light was a longitudinal wave, and that this wave was propagated through a material called the 'aether'. WebTogether he and Geiger related the Compton effect to the theory of Bohr, Kramers, and Slater, and the results of their work provided strong support for the corpuscular theory of light. In 1927 Bothe further clarified, by means of his coincidence method, ideas about light quanta in a paper on light quanta and interference.

Moreover, the … fostair bd

WebSir Isaac Newton (1672) gave the corpuscular theory of light which was also suggested earlier by Descartes (1637) to explain the laws of reflection and refraction. According this theory, light is emitted as tiny, massless (negligibly small mass) and perfectly elastic particles called corpuscles. WebApr 11, 2024 · In physics, total internal reflection (TIR) is the phenomenon in which waves arriving at the interface (boundary) from one medium to another (e.g., from water to air) are not refracted into the second (“external”) medium, but completely reflected back into the first (“internal”) medium. It occurs when the second medium has a higher wave speed (i.e., … http://itg1.meteor.wisc.edu/wxwise/AckermanKnox/chap5/light_theory.html fostair asthma bnf
