That sunshine beaming through your windows might seem completely see-through, but this ‘’white light’’ is actually composed of many colors – a literal rainbow of them. Astronomer Isaac Newton noticed these colors than 300 years ago when he held a special piece of glass called a prism to the sunlight. The prism bent the light into its seven component colors, or wavelengths. Raindrops in the sky act like millions of tiny prisms, scattering the sunlight into its seven colors. A rainbow blossoms into living color when you see it from sunny spot, which is why it looks like rainbows form after a storm.
