An object is placed at a distance of 12 cm in front of a concave mirror. It forms a real image four times larger than the object. Calculate the distance of the image from the mirror.

When an object is placed at a distance of 40 cm from a concave mirror, the size of image is one fourth that of the object. A. Calculate the distance of image from the mirror b. What will be the focal length of the mirror?

An object is placed at a distance of 36 cm from a concave mirror of focal length 12 cm. Find the image distance.

An object of height 20 cm is kept at a distance of 48 cm in front of a concave mirror of focal length 12 cm. If the mirror forms a virtual, diminished image of the object then calculate the distance of the image from the mirror.

An object is placed at a distance of 25 cm from a concave mirror and a real image a formed by the mirror at a distance of 37.5 cm. The magnification of the image will be

A concave mirror of focal length f produces a real image n times the size of the object. The distance of the object from the mirror is

An object is held in front of a concave mirror of focal length 15 cm . The image formed is 3 times the size of the object. Calculate two possible distances of the object from the mirror.

An object is kept in front of a concave mirror of focal length 20 cm. The image formed is three times the size of the object. Calculate the possible distance of the object from the mirror for a real image b. virtual image
