Question:

Which of the following statements are correct?

(A) All mirrors follow the laws of reflection.
(B) The angle between the ray of incidence and the plane surface of the mirror is equal to the angle between the plane surface of mirror and the ray of reflection for plane mirror
(C) the rays coming parallel to the principal axis will go after reflection through the focus of the curved mirror
(D) the rays coming to the pole of a curved mirror making an angle with axis will be reflected making the equal angle with the axis on the other side of the axis.

Choose the correct answer from the options given below:

Options:

(A), (B), (C) and (D)

(A), (C) and (D) only

(A), (B) and (C) only

(B), (C) and (D) only

Correct Answer:

(A), (B), (C) and (D)

Explanation:

The correct answer is Option (1) → (A), (B), (C) and (D)

Explanation:

(A) True — All mirrors obey the laws of reflection irrespective of their shape.

(B) True — For a plane mirror, the angle made by the incident ray with the mirror surface equals the angle made by the reflected ray with the surface (both are complementary to the angle of incidence and reflection with the normal).

(C) True — Rays parallel to the principal axis of a curved mirror pass through (or appear to come from) the focus after reflection.

(D) True — A ray striking the pole of a curved mirror makes equal angles with the principal axis before and after reflection.
