Summary
particle and wave models for light
both models are able to account for the law of reflection an refraction
only the wave model can correctly predict the speed of light in transparent materials; index of reflection n=c/u
interference of light possible under special conditions
diffraction of light produces amazing interference patterns
narrower the opening the wider the diffraction pattern is
in thin films the light rays reflected from the two surfaces and leads to observable interference patterns
light exhibits polarization, demonstrating that it is a transverse wave
