Give the position and nature of image of an extended object for different distances from a concave mmirror.

Calculate the position of image, when an object is placed at a distance of 15 cm from a convex mirror having focal length 0.45 m.

Form the image in case an object is moved from infinity to the concave mirror.

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.

An object of size 5 cm is placed at distance 25 cm in front of a concave mirror of focal length 20 cm. Find the size and nature of image formed ? Also find distance of image from the mirror.

Give the nature, position and size of the image formed by a convex lens when the object lies at 2 F

Establish the relation between object distance, image distance and radius of curvature for a concave mirror.

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

An object is placed exactly midway between a convex and concave mirror each of focal length 15 cm.The two mirror are placed 60 cm apart and the two mirrors face each other.Find the nature and position of the image formed by reflection first at convex and then at the concave mirror.
