Answer:
1.concave mirror has real principle focus
1. convex mirror has virtual principal focus
2.convex mirror has focus behind the mirror
3. focal length of concave mirror = R /2 = 32 / 2 = 16 cm
4. radius of curvature = 2f ,
As we know the focal length in convex mirror is negative so radius of curvature also will be negative
R = 2f
R= 2×(-25)
R = - 50 cm
