Question

. The laws of reflection hold true for _____________ 1

a. plane mirrors only.

b. concave mirrors only.

c. convex mirrors only.

d. all reflecting surfaces.​

Answer 1

Answer:

Option d. all reflecting surfaces.

Explanation:

The laws of reflection hold good for all the mirrors irrespective of their shape (i.e. flat or curved). Laws of reflection states that the incident ray, the normal and the reflected ray all lie in the same plane. The angle of incidence=angle of reflection.

Answer 2

We know that forms of the reflection, the incident ray, the reflected ray and the normal to the reflecting surface all lie in the same plane. Also, the angle of reflection is equal to angle of incidence. The laws of reflection hold true for all reflecting surfaces respective of their shapes weather plane or curved.

(d) all reflecting surfaces is the correct answer.
