The object and the image are at distances x and y respectively from the focus of a concave mirror. Eastablish the relation between x y and the focal length f of the mirror.

Define focal length of concave mirror.

What is the magnification of an object placed at the focus of a concave mirror?

If the object distance and image distance from the focus of a spherical mirror of focal length f be x and y respectively, then

If a graph is drawn taking x and y as the object distance and the image distance respectively from the focus of a spherical mirror, the graph will be a

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 focal length of the mirror is

A small linear object of length I is placed along principal axis of a concave mirror. The neartest point the object is at a distance d from the mirror. If focal length of the mirrors is f then, prove that the size (length) of the image will be l((f)/(d-f))^(2)

An object is kept at a distance of 0.3 m from a concave mirror. If magnification is (1)/(2) , then determine the focal length of the concave mirror.

Show by ray diagram the formation of image of an object placed at the focus of a concave mirror.

Draw a ray diagram for the formation of in a concave mirror when the object is at focus F.

A concave mirror forms an image of an object, magnified 4 times. When the object is moved through 5 cm along the axis of the mirror, the magnification of the image is 5. What is the focal length of the mirror?
