A prism is a piece of glass or other see-through material that has several flat sides, called faces. Many prisms have three long faces in between two triangle-shaped ends. However, prisms can be made in many forms and shapes. People use prisms to bend light.

2020101 — UV-A light has the longest wavelength and lowest energy levels of all the three types. Its wavelength can vary from 315nm to 400nm.

Prisms may be found in binoculars, microscopes, and many other instruments. They help to bend the light that enters these instruments toward the viewer’s eyes. Scientific instruments called spectroscopes use prisms to separate the energy given off by light sources, such as stars. Each chemical that makes up a star produces a different wavelength of light. Scientists can measure the different wavelengths of the light energy to tell what the stars are made of.

Light travels through space in the form of waves. Scientists use an idea called wavelength to describe these waves. Some light waves have long wavelengths, while others have short wavelengths. Each wavelength produces a different color of light. Usually all the wavelengths of light blend together to form white light. But when light enters a prism, it bends. Light waves of different wavelengths bend by different amounts. The longest wavelengths bend the least. The shortest wavelengths bend the most. This bending separates the light waves so each color can be seen. This band of colors—red, orange, yellow, green, blue, indigo, and violet—is called a spectrum.
