Explanation:
An object is placed 20 cm in front of a plane mirror then the image is formed at 20 cm behind the mirror.
If the mirror is moved 2 cm toward the object.
The distance between object and mirror = 20-2 = 18 cm
The distance between image and mirror = 20-2 = 18 cm
Therefore, the total distance between the positions of the original and final image is
d = distance of the original image - distance of the final image
d = 40 – 36
d = 4cm
Hence, The total distance between the positions of the original and final image is 4 cm.
