Spectral analysis measures and analyzes the properties of matter based on the material's interactions with electromagnetic energy. In chemistry and physics, this process is known as spectroscopy. Spectroscopy is of particular use in astronomy, where it is used to determine the chemical composition of celestial objects.Continue Reading
Visible light, magnetic resonance, infrared radiation, X-rays, gamma radiation and ultraviolet radiation are all elements of spectroscopy. Examining the interaction between matter and these different kinds of light reveals different properties about the matter. Research scientists use spectroscopy to detect different types of matter. Astronomers rely on spectroscopy to see objects that do not emit visible light.
Spectroscopy works because different chemical bonds vibrate at different wavelengths when exposed to radiation. Scientists examine the pattern of vibration to determine the chemical makeup of the matter under analysis. A spectroscope is the instrument researchers use to view this pattern.
In addition to its use in astronomy, spectroscopy is a valuable tool in quantum and high-energy physics, crystallography, laser and maser technology, and determining the age and weathering of exposed wood. Molecular spectroscopy is the technology that led to the development of the laser. Spectroscopic analysis of hydrogen allows the development of quantum electrodynamics and the study of increasingly small subatomic particles.Learn more about Physics
Sound energy is a form of energy that is associated with the vibrations of matter. This energy is a mechanical wave, so it needs a transmission medium to pass through, such as air and water.Full Answer >
Einstein's Theory of Relativity is his interpretation on how matter and energy are related, as well as the properties of the fabric of spacetime with respect to gravity. The General Theory of Relativity mainly covers the behavior of the fabric of spacetime around matter, because all matter has mass and therefore gravitational pull. The Special Theory of Relativity addresses the speed of light.Full Answer >
A physicist asks fundamental questions about the interaction between matter and energy and then begins observation and experimentation to answer these questions. Many of the technological advances that humans have today are the results of a physicist's work.Full Answer >
Types of things that are not considered matter include any type of energy, and abstract concepts. Everything in the universe that contains mass is made of matter. However, there are several things, such as heat, light and other forms of energy, that are not considered matter because they lack mass.Full Answer >
