उत्तर
- 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.

A small hole P is made in a piece of cardboard. The hole is illuminated by a torch as shown in the following figure. The pencil of light coming out of the hole falls on a mirror.
At which point should the eye be placed, so that the hole can be seen?
How many times is a ray of light reflected by two plane mirrors placed parallel and facing each other?
Assertion (A): A ray incident along normal to the mirror retraces its path.
Reason (R): In reflection, the angle of incidence is always equal to the angle of reflection.
