PLEASE ANSWER

Kimberli and Sara Grace want to know how rainbows are formed so they both look up rainbows on the internet. Kimberli said she found that light waves come in different wavelengths and frequencies. The color of the light we see is dependent on wavelength. Sarah Grace said the website she found said that the raindrop refracts light and that is why we see the different colors. Who is right and why?

A. Neither is right. Rainbows are caused when light reflects off of the raindrops.

B. Both are right. Refraction causes the different wavelengths to become visible.

C. Sarah Grace is right because the light waves slow down as the enter the raindrop and light is refracted.

D. Kimberli is right because visible light comes in different wavelengths so they move at different speeds.
