Draw a ray diagram to show the path of the refracted ray in each of the following cases:

A ray of light incident on a concave lens is


(i) passing through its optical center.


(ii) parallel to its principal axis.


(iii) directed towards its principal axis

(i) When a ray of light passing through its optical center, then the incident ray is refracted straight which is shown in following diagram:



(ii) When a ray of light is incident on a concave lens, parallel to the principal axis, then the ray diagram is as follows:



(iii) When a ray of light incident on a concave lens directed towards the principal focus, then the ray diagram will be as follows:
