Where would the image be formed by a convex mirror if the object is placed:

1. Between infinity and pole of the mirror?
2. At infinity?

Draw labelled ray-diagrams to show the formation of image in both the cases.

Draw ray diagrams showing the image formation by a concave mirror when an object is placed:Between focus and centre of curvature of the mirror.

What is the difference between a real image and a virtual image? Give one example of each type of image.

With the help of a labelled ray diagram, describe how a converging mirror can be used to give an enlarged upright image of an object.

An object is placed at a distance of 15 cm from a concave lens of focal length 30 cm. List four characteristics (nature, position, etc.) of the image formed by the lens.

An object is placed at a distance of 40cm in front of a convex mirror of radius of curvature 40cm. List four characteristics of the image formed by the mirror.

Describe with a suitable diagram, how a convex mirror diverges a parallel beam of light rays. Mark clearly the pole, focus and centre of curvature of convex mirror in this diagram.

State one practical application the use of such a lens with the object in position (i) and (ii).

If the magnification of an image formed by a mirror is positive, what does it mean?
