Answer 2

Answer:

The line joining the pole and the center of curvature of a mirror is called the principal axis i.e.(C).

Explanation:

Let's analyze the options one by one.

(A) Aperture- The aperture of the spherical mirror equals its diameter. The mirror's reflecting surface.

(B) Principal section- A principal section of a spherical mirror is a segment of the mirror cut by a plane going through its center of curvature and the pole of the mirror.

(C) Principal axis-The straight line that connects the pole (P) with the curvature's center is called the principal axis. The mirror at its pole appears to be normal. Also, called the line joining the pole and the center of curvature of a mirror.

(D)Pole-The focal point of the reflecting surface.

Hence, the correct answer among the given options is (C) i.e.principal axis.
