An object O is kept 80 cm in front of a plane mirror M. If the mirror is moved 20 cm away from the object. Calculate the image shift from its previous position.

Open in App

Solution

Distance of object from the mirror = 80 cm

Distance between object and its image = 80 + 80 = 160 cm

New distance of object from the mirror= 80 + 20 = 100 cm

Now, distance between object and image = 100 + 100 = 200 cm

Image shift = 200 - 160 = 40 cm
