Question

state and explain snell's law​

Answer 1

Answer:

Snell's law states that the relationship between angle of incidences and refraction for a wave impinging on an interface between two media with different incidences of angle is always constant, The law follows from the boundary condition that a wave be continuous across a boundary, which requires that the phase of the wave be constant on any given plane.

hope you get it and mark me as brilliant and thank me!!:-):-)

Answer 2

Explanation:

Snell 's law defined as "the ratio of the sine of the angle of incidence to the sine of the angle of refraction is a constant ,for the light of a given colour and for the given pair of media ".
