An object placed 12 cm from the pole of a concave mirror produces a real image magnified four times.Find the radius of curvature of the mirror.

When does a convex mirror produce a magnified image?

A convex mirror of focal elongth f produces an image magnified m times.The distance of the object from mirror is

When an object is placed beyond centre of curvature of a concave mirror, the image is formed:

In Fig.2.56 ,the direct image formed by the lens(f=10cm) of an object placed of O and that formed after reflection from the spherical mirror are formed at same point.What is the radius of curvature of the mirror? .

An object is placed in front of a concave mirror of radius of curvature 40 cm at a distance of 10 cm.Find the position and magnification of the image.

An object is placed in front of convex mirror 20 cm radius of curvature.Its image is forced 8 cm behind the mirror.Find the distance of the object from the miror.

Find the position of an object,which when placed in front of a concave mirror of focal length 20 cm,produces a virtual image,which is twice the size of the object.

An object is placed at a distance of 36 cm from a convex mirror.A plane mirror is placed in between, so that the two virtual images so formed coincide.If the plane mirror is at a distance of 24 cm from the object,find the radius of curvatrure of the covex mirror.

An object is placed in front of a concave mirror of radius of curvature 30 cm at a distance of10 cm.Find the position,nature and magnification fo the image.
