Answer-
The focal length of the given spherical mirror is 25cm
Solution-
We have-
Radius of curvature,
R = 50 cm
Radius of curvature of a spherical mirror
= > 2 x focal length(f)
=> R = 2f
=> f = R/2
=> f = 50/2
=> f = 25cm.
Hence, the focal length of the given spherical mirror is 25cm

Answer:
we know that,
radius of curvature = 2 ×focal length
so radius of curvature=50
50=2×focal length
50÷2= focal length
