उत्तर
All the three surfaces
Explanation:
Laws of reflection are always followed whatever be the surface of the object.
Therefore, the angle of incidence is equal to the angle of reflection on ail the three surfaces (S1, S2 and S3).

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?
Diffused reflection gives a sharp image.
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.
