Question

State snell's law of refraction

Answer 1

Snell's law of refraction states that the ratio between the values of sine of angle of incidence and sine of angle of refraction for two given optical media is a constant quality ie μ=sin i/ sin r

Answer 2

Snell’s law tells us the degree of refraction and relation between the angle of incidence, the angle of refraction and refractive indices of given pair of media. We know that light experiences the refraction or bending when it travels from one medium to another medium. Snell’s law predicts the degree of the bend. It is also known as the law of refraction. In 1621, Willebrord Snell discovered the law of refraction, hence called Snell’s law.
