A person wants a real image of his own, 3 times enlarged. Where should he stand in front of a concave mirror of radius of curvature of 30cm.

The position of an object placed 5 cm in front of concave mirror of radius of curvature 15 cm is

An object is placed at a long distance in front of a convex mirror of radius of curvature 30 cm. State the position of its image.

The minimum sum of the distances of a real object and a real image from a concave mirror of radius of curvature 20cm is:

An object is placed at a large distance in front of a convex mirror of radius of curvature 40 cm. How far is the image behind the mirror?

An object is placed 15 cm in front of a convex lens of focal length 10 cm . Find the nature and position of image formed. Where should a concave mirror of radius of curvature 20 cm be position of the object itself ?

A linear object of heigth 10 cm is kept in front of concave mirror of radius of curvature 15 cm, at distance of 10 cm. The image formed is

An object is placed 15 cm in front of a convex lens of focal length 10 cm . Find the nature and position of image formed. Where should a concave mirror of radius of curvature 20 cm be placed so that the final image is formed on the position of the object itself ?
