The fact that light could be polarized was for the first time qualitatively explained by Newton using the particle theory. Étienne-Louis Malus in 1810 created a mathematical particle theory of polarization. Jean-Baptiste Biot in 1812 showed that this theory explained all known phenomena of light polarization. At that time polarization was ...
About 2% of the light beam is reflected at the air-water interface. So 98% continues on through, and 2% of this reflects from the back surface of the film. These two reflected beams emerge parallel to each other. They differ in distance traveled from the front surface by about twice the thickness of the film.

Nov 11, 2023 · Newton used a board with a hole in it to screen off all the spectrum except for a single color — red, say — and then allowed that colored light to pass through the second prism.

analyse the experimental evidence that supported the models of light that were proposed by Newton and Huygens (ACSPH050, ACSPH118, ACSPH123)
At an early age, Newton has always been interested in the theory of light. Newton's model of light proposes that propagation of light is caused by the rectilinear motion of light particles which he termed light corpuscles. These light particles travel at a finite speed and their interactions with the external environment e.g. rigid surfaces, walls ...
Huygens' model of light assumes light behaves as a longitudinal wave. Huygens understood light’s propagation as a wave’s direction of travel. He proposed that the nature of light can be better understood by observing the motion of water surfaces. 1. Oscillation 2. Crests 3. Troughs 4.

Determination of speed of light contributed to the shift from Newton's corpuscular model of light to Huygens' wave model.
Foucault measured the speed of light in an experiment involving mirrors. Newton proposed the boundary between adjacent media would exert a force on light corpuscles therefore causing them to accelerate. When light corpuscles enter a medium with greater refractive index (e.g. from air to water), the force of attraction is stronger and thus they will increase in velocity. In contrast, Huygens proposed that light waves would travel slower in a medium with greater refractive index. This was exper...
Since almost everyone agreed that light must be composed of either particles or waves, Newton used the failure of the wave theory to prove that light is made of particles. Newton concluded that light is composed of coloured particles that combine to appear white. [4] Newton’s crucial experiment.
In 1801 Young did the famous double-slit interference experiment. This seemed to definitely prove that light behaves like waves by showing that light plus light can result in darkness (destructive interference). He used his theory to explain such things as Newton rings and the rainbow supernumerary arcs.
