The distance of the image of a point (or an object) from the line of symmetry (mirror) is ________ as that of the point (object) from the line (mirror).

Find the image of the point with respect to line mirror.

Assertion : When object moves in a direction perpendicular to a fixed plane mirror then velocity of image with respect object is double in magnitude to the magnitude of velocity of object. Reason : Distance of image from the plane mirror is always same as distance of object from the plane mirror.

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 at a distance of 10 cm from a concave mirror and the image of the object is at a distance of 30 cm from the mirror on the same side as that of the object. The radius of curvature of the concave mirror is

The image formed by a concave mirror is twice the size of the object. The focal length of the mirror is 20 cm. The distance of the object from the mirror is//are

The image (of a real object) formed by a concave mirror is twice the size of the object. The focal length of the mirror is 20cm. The distance of the object from the mirror is:
