The two types of spherical mirrors are ...............

• flat and plane

• concave and plane

• convex and concave

• plane and rectangular

If 'R' is radius of curvature and 'f' is focal length of a spherical mirror then the correct relation between the two is

• R = f

• R = f/2

• f = 2R

• f = R/2
