A concave lens is placed in the path of a uniform parallel beam of light falling on a screen as shown. Then :-

Options:(select one or more)

Answer:
B, D
Solution:

The concave lens diverges the parallel beam outward, away from the axis.

Rays that would have reached region AB are spread toward C and D, so region AB gets less light - (B) correct.

The deflected rays add to the light in regions AC and BD, so the intensity there increases - (D) correct.
