Solution

Convex mirror and concave mirror.

  Convex mirror Concave mirror
1. It is called a diverging mirror.  It is called a converging mirror.
2.  The light is reflected from the outer surface. The light is reflected from the inner surface.
3. It can form only a virtual image It can form a real image as well as a virtual image. 
4. According to sign convention, the focal length is positive. According to sign convention, the focal length is negative.

A 4 cm tall object is placed on the principal axis of a convex lens. The distance of the object from the optical centre of the lens is 12 cm and its sharp image is formed at a distance of 24 cm from it on a screen on the other side of the lens. If the object is now moved a little away from the lens, in which way (towards the lens or away from the lens) will he have to move the screen to get a sharp image of the object on it again? How will the magnification of the image be affected?
