Solution
- The angles are labelled wrongly in diagram (a). The angle of reflection is labelled as angle of incidence and vice versa.
- In diagram (b), the law of reflection is not followed as angle of reflection and angle of incidence are not equal in measure.
-
The normal drawn is not perpendicular to the surface in diagram (c).
The corrected ray diagram is as shown below.
