How do rainbows form? This is a good question. The raindrops act as little prisms. Prisms refract light into ROYGBIV. The rainbow is made up of ROYGBIV. The raindrops refract light which creates rainbows. This is not an overly complex process. When it rains, the raindrops refract the white light, and a rainbow is created. ROYGBIV is red, orange, yellow, green, blue, indigo, and violet. Red has long wavelengths, and low frequency. Violet has shorter wavelengths with higher frequency. As you move left to right in ROYGBIV, the wavelengths decrease, and the frequency increases. If you move from right to left the wavelength increases, and the frequency decreases.
Rainbows can also form if you pass white light through an actual prism. The prism than refracts the light which creates ROYGBIV. Red has longer wavelengths, and lower frequency. On the other hand, violet has shorter wavelengths, but higher frequency. This is how rainbows form.
