The focal length of a concave mirror is f and the distance of the object from the principal focus is x . The magnification of the image produced is

The focal length of convex tens is f and the distance of an object from the principal focus is x. The ratio of the size of the real image to the size of the object is

The focal length of convex tens is f and the distance of an object from the principal focus is x. The ratio of the size of the real image to the size of the object is

Focal length of a concave mirror is f. The distance from its focal point to the object is P. Find the ratio of heights of 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 ?

The focal length of a concave mirror is 30 cm.Find the position of the object in front of the mirror,so that the image is there times the size of the objects.

Assertion : The focal length of the mirrorr is f and distance of the object from the focus is u , the magnification of the mirror is f//u . Reason : Magnification =("Size of the image")/("Size of object" )

The focal length of a concave mirror is f. A point object is placed at a distance of xf on the right side of the focus. The magnification of the image will be
