Question

The distance between the pole and principal focus of a spherical mirror is 10 cm. What is the focal length of the mirror?

Answer 1

Answer:

Explanation:

Light rays that are parallel to the principal axis of a concave mirror converge at a specific point on its principal axis after reflecting from the mirror. This point is known as the principal focus of the concave mirror. Hence, the focal length of the given spherical mirror is 10 cm.

Answer 2

Answer:

10cm

Explanation:

Focal length is the distance between the pole and principal focus of a mirror. Since the distance is 10cm , the focal length = 10 cm
