This dispersion of light allows us to see the spectrum of colors that form a rainbow 2. Therefore, white light is split up after passing from air to water and the individual colors become visible. Because lights of different colors have different wavelengths, each color is refracted by different amounts. The shorter the wavelength, the more it bends. How much a light is refracted depends on the wavelength of the light. This is known as refraction of light 1 (More light experiments). When light passes from one medium to another medium of a different density (e.g. That is because light mixing is additive while pigment mixing is subtractive. You may wonder why when you mix all the different colors of paint together result in black instead of light. The different rainbow colors are essentially mixed together to result in a white color. Sunlight or white light is a mixture of all the rainbow colors. This experiment is an engaging way to introduce children to the basics of optics and the physics of light. Some types of atoms have more electrons than others. The result is a beautiful display of the colors of the rainbow, which can be used to teach about the nature of light and color. The atoms that make up everything around you, from the air you breathe to the change in your pocket, have electrons. It involves using a light source, such as sunlight or a flashlight, and a medium to separate the light into its component colors. Making a rainbow is a fun and educational science experiment that can be easily done at home or in the classroom.
