Question

what happens when the incident ray strike on the surface of the prism with angle equal to Critical Angle and it is coming from the medium to denser ..​

Answer 1

Answer:

Explanation:

When the angle of incidence is equal to the critical angle, the angle of refraction is equal to 90°. If the angle of incidence is bigger than this critical angle, the refracted ray will not emerge from the medium, but will be reflected back into the medium. This is called total internal reflection.

When the angle of incidence is equal to the critical angle, the angle of refraction is equal to 90°. If the angle of incidence is bigger than this critical angle, the refracted ray will not emerge from the medium, but will be reflected back into the medium. This is called total internal reflection
