Refractive index of water is 4 by 3 find critical angle
Hello Sashank,
Hope you are doing well.
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°
Good luck
