![]() ![]() If you have Netflix check out a show called StoryBots. The order of the wavelengths do not change, rainbows will always be in this order. Colors maintain their wavelengths and are refracted the same way every time, creating rainbows. Rainbows are always seen in the same order: red, orange, yellow, green, blue, indigo, and violet. Black is when all the wavelengths are absorbed. When you see white, what you are actually seeing is all the wavelengths mixed together, all colors are being reflected. So an apple looks red because the surface of it absorbs all colors except red. What we recognize as the color of an object is actually the wave of light that is reflected by that surface while all other wavelengths are absorbed. Reds have a low frequency and high wavelength, while the purples have a high frequency and low wavelength. These differences in light waves are what give us colors.Ĭolors each have different frequencies and wavelengths. Frequency is how quickly a wave moves up and down, and the wavelength is the distance between two peaks in the waves. These differences are the frequencies and wavelengths. Some are fast, others are more spread out. It’s pretty interesting, but for our purposes, we are thinking of light as a wave.) Think of the waves you see when you drop a penny in a pool. How do we see it? We see colors because they are in the visible light spectrum. Let’s take a moment to talk about how color actually works.
