1 The incident ray, the refracted ray and the normal to the interface of two transparent media at the point of incidence, all lie in the same plane. 2 The ratio of sine of angle of incidence to the sine of angle of refraction is a constant, for the light of a given color and for the given pair of media. This law is also known as Snell’s law of refraction.This constant value is called the refractive index of the second medium with respect to the first.

what is the significance of davisson germer experiment

Divisson Germer experiment proved that electron behaves as wave, since diffraction was caused by waves; its a property associated with wave. But then, long ago when electron was discovered by J.J. Thompson. He found it as a particle in cathode ray tube. So, Because of validity of both of these experiments, we led to the conclusion that electron behaves as particle as well as wave, under appropriate conditions.
