Question

A ray of light falss on a transperant glass slab of refractive index root2 if the reflected and refracted rays are murtually perpendicular then the angle of incidemce

Answer 1

Answer:

depends on its angle of reflection

Explanation:

if angle of incidence is given angle reflection could be taken out and if angle reflection is given then angle of incidence could be found

Answer 2

Answer:
