A ray of light is incident on one face of prism making an angle of `50^@` with the face. If emergent ray from the prism is made to retrace its path, what would be the angle of emergence ?

Verified by Experts

As `50^@` is angle with face of prism, therefore, `i= 90^@ - 50^@ = 40^@`.
When emergent ray is made to retrace its path, entire path of the ray is retrached. Therefore, `e = i= 40^@`.
