A peson looks into a spherical mirror. The size of image of his face is twice the actual size of his face. If the face is at a distance of 20cm, then find the radius of curvature of the mirror.

A convex mirror forms a real image 5 times the size of the object placed at a distance of 20 cm from it. The radius of curvature of the mirror is

A virtual image of half the size of the object is formed by a convex mirror at a distance of 30 cm from the object. What is the radius of curvature of the mirror?

You are asked to design a shaving mirror assuming that a person keeps it 10cm from his face and views the magnified image of the face at the closest comfortable distance of 25cm . The radius of curvature of the mirror would then be:

Look at . What is the radius of curvature of the spherical mirror? Given PA=10 cm.

A concave mirror forms a virtual image of size twice that of the object placed at a distance 5 cm from it . Find the focal length of the mirror.
