When the distance of an object from a concave mirror is decreased from `15 cm` to 9 cm, the image gets magnified `3` times than that in first case. Calculate focal length of the mirror.

An object is placed at a distance of 10 cm from a concave mirror. When the distance of object from the mirror is decreased to 6 cm, the image gets 2 times magnified than that in first case. Calculate the focal length of the mirror.

If an object is 30 cm away from a concave mirror of focal length 15 cm the image will be

How far should an object be placed from a concave mirror of focal length 15 cm so as to get an image magnified two times?

An object is placed at a distance of 30 cm from a concave mirror of focal length 15 cm. The image will be

An object is placed in front of a concave mirror at a distance of 7.5 cm from it. If the real image is formed at a distance of 30 cm from the mirror, find the focal length of the mirror. What would be the focal length if the image is virtual.

An object is placed in front of a concave mirror at a distance of 7.5 cm from it. If the real image is formed at a distance of 30 cm from the mirror, find the focal length of the mirror. What would be the focal length if the image is virtual.

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 is placed at the distance of 30 cm from a concave mirror of focal length 15 cm. The image will be-

A concave mirror forms an erect and there times magnified image on the axis of the mirror at a distance of 32 cm from the object. What is the focal length of the mirror?
