Question

b) Define focal length of a convex mirror. Write the relationship
between focal length and radius of curvature of a convex mirror.​

Answer 1

Explanation:

Focal length is the distance between the center of a convex lens or a concave mirror and the focal point of the lens or mirror — the point where parallel rays of light meet, or converge

Answer 2

Answer:

Focal length. Focal length is the distance between the center of a convex lens or a concave mirror and the focal point of the lens or mirror — the point where parallel rays of light meet, or converge.

The distance from the pole to the focal point is called the focal length (f). The focal length of a spherical mirror is then approximately half its radius of curvature. It is important to note up front that this is an approximately true relationship.
