Question

state Snell's law of refraction
​

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

Answer 2

Snell s law states that ratio of sin of angle of incidence to sin of angle of refraction is constant

sini/sinr = constant
