Question

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

Answer 1

Answer:So the critical angle is defined as the angle of incidence that provides an angle of refraction of 90-degrees. Make particular note that the critical angle is an angle of incidence value. For the water-air boundary, the critical angle is 48.6-degrees.
