At which position of object will be the magnification be 1 in case of
concave mirror?

Define magnification of spherical mirror. What is the magnification produced in a plane mirror?

Find the position of an object,which when placed in front of a concave mirror of focal length 20 cm,produces a virtual image,which is twice the size of the object.

A concave mirror of focal length 20 cm and a convex mirror of focal length 15 cm are placed 50 cm apart,such that the two mirrors face each other .An object is placed exactly midway betwen them.Find teh nature and position of the image formed by reflection first at the concave mirror and then at the convex mirror.

Explain the sketches the formation of a virtual image in the case of a concave mirror.

Use the mirror equation to deduce that: an object placed between the pole and focus of a concave mirror produces a virtual and enlarged image.

A 4.5 cm needle is placed 12 cm away from a convex mirror of focal length 15 cm. Give the location of the image and the magnification. Describe what happens as the needle is moved farther from the mirror.

An erect image of 3 tiems the size of the object is obtined with a conccave mirror of radius of curvature 36 cm.What is the position of the object?
