Question

State the law of refraction of light that defines the refractive index of a medium
with respect to the other. Express it mathematically.
​

Answer 1

Answer:

First law of refraction also known as Snell's law defines the refractive index of a medium with respect to the other medium. First law of refraction states that, the ratio of the sine of the angle of incidence to the sine of the angle of refraction is constant. This is known as Snell's law.......
