Question

A ray of light makes an angle of 50 degree with surface one its angle of incidence will be

Answer 1

Answer:

angle of incidence = 40 degree

Explanation:

The normal ray, at the point of incidence, is perpendicular to the surface AB. Therefore, if the incident ray forms an angle of 50 degrees with the surface, it will form an angle of 90 - 50 or 40 degrees with the normal ray. As the angle of incidence is 40 degrees, the angle of reflection will also be 40 degrees
