Question

which one of the following is focal length of the convex mirror whose radius of carvature is 32 cm

Answer 1

radius of curvature =R=32cm
focal length =f

now we know that
2f=R
2f=32
f=32/2
f=16cm

therefore the focal length of the convex mirror with radius of curvature 32, is 16

hope it helps u
