Question

The imaginary line connecting the pole and the focus of a curved mirror is called its longitude.

• A. True
• B. False

Answer 1

The correct option is B False

1. Pole is the point at the middle of the spherical mirror.
2. Focus is a point at which all the rays from the point object and parallel to the spherical mirror meet or appear to meet.
3. The straight line passing through the pole and the centre of curvature of the spherical mirror is called the principal axis of a spherical mirror
4. The imaginary line joining the pole and the focus of a curved mirror is the principal axis.

Hence, the given statement is false.
