what is refraction? what is the laws of refraction?

Answer»

no that is reflection. I mean refraction

Refraction is the phenomenon of change of direction of wave due to change of its transmission medium.Laws of refraction:1) Snell's law:ratio of sine of angle of incidence to the angle of refraction is always constant for two given media.2) incident Ray , refracted Ray and normal Ray all like on the same plane.
