An X-ray is a quick and painless procedure commonly used to produce images of the inside of the body. It's a very effective way of looking at the bones and can be used to help detect a range of conditions.-rays can be used to examine most areas of the body. They're mainly used to look at the bones and joints, although they're sometimes used to detect problems affecting soft tissue, such as internal organs. Problems that may be detected during an X-ray include: 1  bone fractures and breaks.
Spectrometer, Spectroscope, and Spectrograph. A spectrometer is any instrument used to probe a property of light as a function of its portion of the electromagnetic spectrum, typically its wavelength, frequency, or energy. The property being measured is usually intensity of light, but other variables like polarization can also be measured.
A spectroscope is similar to a prism in that it can break up light into its component. At one end of the spectroscope is a square film of material that acts like a prism. The film is called a diffraction grating. It is made by putting thousands of grooves on a plastic film.This bends the light coming through it and, in essence, causes the light to spread out into its different wavelengths of light (colors). This is the end of the spectroscope you look through.he film is called a diffraction grating. It is made by putting thousands of grooves on a plastic film.
