Question

A Ray of light from a denser medium strikes a real medium at an angle of incidence I .if the reflected and refracted rays are mutually perpendicular to each other then what is the value of critical angle .......

Answer 1

Answer:

A ray of light from a denser medium strikes a rarer medium at an angle of incidence i. The reflected and refracted rays make an angle of π/2 with each other. If the angles of reflection and refraction are r and r′, then the critical angle will be.
