X-rays are a form of electromagnetic radiation, as are radio waves, infrared radiation, visible light, ultraviolet radiation and microwaves. One of the most common and beneficial uses of X-rays is for medical imaging. X-rays are also used in treating cancer and in exploring the cosmos.
A spectroscope is a scientific instrument that splits light into its different wavelengths, which humans see as different colors. Violet has the shortest wavelength that people can see and red the longest. This instrument can also identify wavelengths that humans cannot see, such as infrared and ultraviolet radiation.
An early example of a spectroscope. Prisms split light by refraction; the resulting spectrum is measured by the spectroscope. In astronomy, a spectroscope may be used in conjunction with a telescope. A spectrophotometer measures how much light is reflected off of -- or absorbed by -- an object.
