There is a mistake in each of the following ray diagrams given as Fig. 16.9 a, b, and c. Make the necessary correction (s).

Explanation

case(a):Direction of ray of light is wrong in this case.this should be in opposite direction such that ray should travel from incident ray to reflected ray.
case(b):In this case the angle of incident is not equal to the angle of reflection, this should be same.
case(c):The normal should be perpendicular to the surface of reflection.
