Question

focal length of a
length of a concave mirror
con cave mirror is 30cm then
Radius of curvature is
a
300m b) 60cm C) 15cm
d) ocm​

Answer 1

Answer:

please mark as brainiest

Explanation:

focal length= 1/2 radius of curvature

1/2x= 30

x=60cm

therefore radius of curvature is 60cm

Answer 2

Answer:

The focal length of a concave spherical mirror is half the radius of curvature in front of the mirror’s center. So the focal length of your mirror would be -15 cm.
