Focal length of convex mirror `M_1` is 20 cm and that of concave mirror `M_2` is 30 cm .Find position of second image `I_2`.Take first reflection from `M_1`.

The focal length of a concave mirror is 15 cm. if the object distance is 20 cm, find the Position and nature of the image.

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.

A concave mirror of focal length 20 cm is placed 40 cm away from a convex mirror of focal length 15 cm . An object is placed between both the mirrors, 15 cm away from the convex mirror. Find the position of image formed by reflection from concave mirror followed by convex mirror. What is nature of the image formed ?

A concave mirror of focal length 36 cm and a convex mirror of focal length 20 cm are placed face to face on the same axis at a distance of separation 80 cm. An object is placed at a distance 20 cm in front of the convex mirror. Determine the position of the images (i) first by the reflection in convex mirror and then in the concave mirror and (ii) first by the reflection in concave mirror and then in the convex mirror.

Two mirrors, one concave and the other convex, are placed 60 cm apart with their reflecting surfaces facing each other. An object is placed 30 cm from the pole of either of them on their axis. If the focal lengths of both the mirrors are 15 cm, the position of the image formed by reflection, first at the convex and then at the concave mirror, is:

Two mirrors, one concave and the other convex, are placed 60 cm apart with their reflecting surfaces facing each other . An object is placed 30 cm from the pole of either of them on their axis. If the focal lengths of both the mirrors are 15 cm , the position of the image formed by reflection, first at the convex and then at the concave mirrors , is

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.
