Question

WhatImage distance

Answer 1

The distance at which the object is placed from that of the point of incidence on the mirror is called as object distance. Similarly, the distance from the point of incidence of the mirror to where the image is formed isimage distance.

Answer 2

• The distance at which the object is placed from that of the point of incidence on the mirror is called as object distance. Similarly, the distance from the point of incidence of the mirror to where the image is formed is image distance.
• The image distance is the distance from the thin lens to the image. The focal length is a characteristic of the thin lens, and it specifics the distance at which parallel rays come to a focus. If the object distance is very large compared to the focal length it is considered to be at infinity.
