An object is placed 42 cm, in front of a concave mirror of focal length 21 cm. Light from the
concave mirror is reflected onto a small plane mirror 21 cm in front of the concave mirror
Where is the final image?

Text Solution

Verified by Experts

O is placed at centre pf curvature of concave mirror `(=42 cm)`.Therefore ,image from this mirror `I_1` will coincide with object O.

Now plane mirror will make its image `I_2` at the same distance from itself.
