What is snell s law |
|
Answer» The ratio of sine of angle of incidence to the sine of angle of refraction is constant , for a light of given colour and for a given pair of media. This is known as snell\'s law of refraction. Sini =Sinr The ratio of sin of angle of incident to sin of angle of refraction is always constant.Sin i/Sin r =u (mu).It is called snell\'s law |
