A convex mirror of focal length 10cm is placed in water.If the refractive index of water is 1.33. What will be the focal length of the convex mirror in water?

Answers

Answered by manetho

Answer:

10 cm

Explanation:

For any mirror convex or concave focal length remains constant irrespective of the medium it is placed in. Therefore, the focal length of the convex mirror remains to be 10 cm only. However, in case of lens the focal length does depend upon the medium it is placed in.

Given:

A convex mirror of focal length 10cm is placed in water. If the refractive index of water is 1.33.

To find:

What will be the focal length of the convex mirror in water?

Solution:

The focal length of the convex mirror in water is 10 cm.

The focal length of concave/convex mirrors does not depend on the external medium in which it is held.

So, there will be no change in the focal length of the mirrors when immersed in water.
