hii
​

Answer 1

Explanation:

Relation between focal length and Radius of curvature for a concave mirror: Consider a concave mirror and a ray AB which is parallel to the principal axis and incident at the point B. After reflection from the mirror, this ray passes through its focus F as per the laws of reflection.

Answer 2

Answer:

fl= distance between the centre of curvature and radius

r of c= distance between the focal length and centre of curvature
