A concave mirror of focal length f (in air) is immersed in water (mu = (4)/(3)) . The focal length of the concave mirror in water will be

A convex mirror of focal length f (in air) is immersed in water (mu = 4/3) . The focal length of the mirror in water will be -

Focal length of a concave mirror is

Focal length of a concave mirror is

Define focal length of concave mirror.

Assertion : The radius of curvature of a mirror is double of the focal length. Reason : A concave mirror of focal length f in air is used in a medium of refractive index 2. Then the focal length of mirror in medium becomes 2f.
