Why are there different colors of visible light? How do you know? A Colored light travels through space. "There is a lot more to light than just the light that we can see. We use all the different types of light every day, and it travels in waves through the universe." B Prisms change colors into different types of light. "Visible light has different colors that we can see. In 1665, the scientist Isaac Newton showed that a prism bends visible light into different colors." C Different wavelengths create different colors of light. "Violet is at one end of the rainbow because it has the shortest wavelength. Red is at the other end because it has the longest wavelength." D Different temperatures change light into different colors. "Sometimes, color gives us information about temperature. The flames from a fire are a good example of how color reflects temperature."
