triangular prism rainbow

Have you ever seen a rainbow? That is always beautiful sight and gives us happiness! The proper name for a rainbow is a refraction of light through small droplets of water suspended in the atmosphere. This bending forms a spectrum of colors in an arch in the sky. However, did you know that you can also obtain a rainbow from a triangular prism? It’s true!

It is not an ordinary shape but a unique shape called a triangular prism. One end has a triangle and the other end has a rectangle. If you take a beam of light and place it through a triangular prism at some angle and place it to a white screen, you can see a spectrum of colors. This is because as it passes through the prism the light bends which divides into several colors. That you can see so many colors from only one beam of light, like magic!

The Science Behind a Beautiful Triangular Prism Rainbow

Light passing through a triangular prism will first bend toward the base of the prism. Then as it exits the prism, it bends away from the base and disperses into its 7 colors. Its this bending and hiking apart that makes the great old rainbow. Isn't it incredible that one simple thing can build something so beautiful?

You may ask your self about how does the color of a rainbow are arranged. It’s not just random! The order of the colors is always the same. In a rainbow, red is the outer band and violet is the inner. Different colors have different wavelengths, that is, the distances between waves of light, so this is a special order.
