If you are standing in front of a mirror and observing your own image what is the relation between the distance of the object and the image from the mirrorr?

Draw a ray diagram to show how the image is formed when the object is placed between f and 2 f distances from a convex lens.Deduce the relation between the distances of he oject and the image from the lens and the focal length of the lens under this condition.

An object is placed in front of convex mirror 20 cm radius of curvature.Its image is forced 8 cm behind the mirror.Find the distance of the object from the miror.

If a concave mirror of focal length f produces a real image n times the size of the object,then find the distance of the object from the mirror.

You have learnt in the text how Huygens of reflection and refraction. Use the same principle to deduce directly that a point object placed in front of a plane mirror produces a virtual image whose istance from the mirror is equal to the object distance from the mirror.

We wish to obtain an erect image of an object, using a concave mirror of focal length 15cm what should be the range of distance of the object from the mirror? What is the nature of the image ? Is the image larger or smaller than object? Draw a ray diagram to show the image formation in this case.

What is minimum distance between an object and the real image formed by a convex lens?
