In a mirror, object distance=Image distance. Name the mirror.

You have learnt in the text how Huygens of reflection and refraction. Use the same principle to deduce directly that a point object placed in front of a plane mirror produces a virtual image whose istance from the mirror is equal to the object distance from the mirror.

An object is at a distance of 10 cm from a spherical mirror and the image of the object is at a distance of 30 cm from the mirror on the same side as the object.Is the mirror concave or convex?What is its focal length?

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

Choose the correct option: David is observing his image in a plane mirror. The distance between the mirror and his image is 4m. If he moves 1m towards the mirror, then the distance between David and his image will be:
