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.
The radius of this path depends upon the mass of the particles (all other factors, such as velocity and charge, being equal). Thus, if in the original stream isotopes of various masses are present, the position of the blackened spots on the plate makes possible a calculation of the isotope masses.The mass spectrograph is widely used in chemical analysis and in the detection of impurities.
