Question

Ray of lght poes from glass to air by an angle of incidence 30⁰ The refractive index of glass if angle of refraction 60⁰ will be​

Answer 1

Answer:

Snell's law states that ratio of sine of angle of incidence to sine of angle of refraction is a constant. This constant is called the refractive index of the medium. Hence:
