It is desired to obtain an erect image of an object using a concave mirror of focal length 20 cm
What can be the range of distance of the object 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.

A convex mirror of focal elongth f produces an image magnified m times.The distance of the object from mirror is

The image of an object formed by a convex mirror is always…..

In order to obtain a real image of magnification 2 using a convergin lens of focal length 20 cm,where should an object be placed?

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.

An object of size 5 cm is placed at distance 25 cm in front of a concave mirror of focal length 20 cm. Find the size and nature of image formed ? Also find distance of image from the mirror.

An object is at a distance of 5 m from a convex mirror of focal length 10 cm.Where is he image formed ?

An object is placed at a distance of 40 cm from a concave mirror of focal length 15 cm.If the objects is displaced through a distance of 20 cm towards the mirror,by how much distance is the image displaced.
