A linear object is placed along the axis of a mirror as shown in figure. If 'f' is the focal length of the mirror then the length of image is-

A small linear object of length b is situated along the axis of a concave mirror at a distance x. If the focal lenght of the mirror is f, the length of the image will be

A point object is placed on the axis of the concave mirror at a distance of 60 cm from the focal point of the mirror. Its image is formed at the point of object then focal length of the mirror is

An object is placed on the principal axis of a concave mirror at a distance of 1.5 f(f is the focal length). The image will be at,

An objects is placed at a distance equal to focal length of convex mirror.If the focal length of the irror be f,then the distance of the image from the pole of the mirror is:

A short linear object of length b lies on the axis of a concave mirror of focal length F at a distance u from the pole. The length of the image will be

The distance of an object from a spherical mirror is equal to the focal length of the mirror. Then the image:

The distance of an object from a spherical mirror is equal to the focal length of the mirror. Then the image:

The distance of an object from a spherical mirror is equal to the focal length of the mirror. Then the image.
