An object is placed in front of a convex mirror on the principal axis. With the help of a ray diagram show the position of the image.

An object is placed at a distance of 20 cm in front of a concave mirror of focal length 10 cm. Determine the position of the image. What is the ratio of the size of the image to the size of the object ?

A cube is placed in front of a large concave mirror. Will the image of the cube be a cube ?

Where should an object be placed in front of a concave mirror to get a magnified image ?

An object is placed in front of a convex lens at a distance twice of focal length.A concave mirror is on the other side of the lens. The distance between lens and mirror is twice of the sum of their focal length.Find image distance, nature of image and the magnification.

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

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.

An object is placed in front of a concave mirror, a three times magnified image is formed. If the object is moved through a distance 20 cm towards the mirror, a virtual image of same magnification is formed. What is the focal length of the mirror?

An object is placed at a distance x from the principal focus of a spherical mirror of focal length f. The magnification of the image will be
