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

Calculate the distance d,so that a real image of an object at O,15 cm in front of a convex lens of focl length 10 cm be formed at the same point O as sohwn in Fig.2.45. te radius of cuvature of the mirro is 20 cm.Will the image be inverted or erect? .

Where will the real and inverted image of an object placed at the centre of curvature of a concave mirror will be formed?

Describe with the help of diagram the natrue, size and position of the image formed when and object placed at centre of curvature of a concave mirror.

A concave mirror has a focal length of 10 cm and an object is placed at a distance of 16 cm from it.Find the psition of the image formed by it.

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.

A concave mirror has a focal length of 20 cm and an object is placed at a distance of 16 cm from it.Find the position of the image formed by it.
