Question

If a convergent beam of light passes through a diverging lens, the result
(A) may be a convergent beam
(B) may be a divergent beam
(C) may be a parallel beam
(D) must be a parallel beam

Answer 1

Answer:

a) May be a convergent beam

Answer 2

Answer:

It is for sure that diverging lens will try to diverge the light rays but when diversion is enough then output beam may be a divergent one but when diversion is not enough then output beam may remain a convergent one. Hence, options (c) and (d) are correct. There is also one possibility that output beam is parallel but it is not necessary. Hence, option (a) cannot be correct.
