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.

Admin I think Prism is correct Ans, as the rain drops act like prism after it gets refracted from sunlight.
Answer should be Prism coz refraction, total internal reflection and dispersion occur in a prism.
Its prisms please correct it.
Not mirror
Act like a prism
As prism divide white light into 7 colours
It will be prism
prism is correct answer
prism is correct answer
it should be prism not mirror coz when light enters through the prism the process of refraction takes place and light disperse into 7 different colors.
Prism (not mirror) please correct it
it acts like as prism please correct it
admin please correct the option as there is already an explanation beneath the question which is the proof that prism is the correct answer
Plz correct the answer

It’s act like a prism.
Prism is the right answer
