Rainbow is seen after rain because of hanging molecules of water which act as – (1) lenses (2) mirrors (2) prisms (4) slabs

1 Answer

Answer :

(2) mirrors Explanation: In optics, a prism is a transparent optical element with flat, polished surfaces that refract light. In a rainbow, raindrops in the air act as tiny prisms. Light enters the raindrop, reflects off of the side of the drop and exits. In the process, it is broken into a spectrum just like it is in a triangular glass prism.
