Question

the absolute refractive index of water 4/3. what is the critical angle​

Answer 1

Answer:

Given, the absolute refractive index of water is said to be 4/3.

Assume, the critical angle is said to b C. Stating, Snell’s Law, C is equal to sin^-1(1 divided by refractive index) C is equal to sin^-1(3 divided by 4) C is equal sin^-1(0.75) C is equal 48.59°
