what would the metals by the color of flame look like when they burn Spectroscopy is the study of the interaction between matter and radiated energy. Historically, spectroscopy originated through the study of visible light dispersed according to its wavelength, by a prism. The concept was expended to comprise any interaction with radiative energy as a function of its wavelength or frequency. Spectroscopic data is often represented by a spectrum, a plot of the response of interest as a function of wavelength or frequency. Spectrometry and spectrography both refer to the measurement of radiation intensity as a function of wavelength and are often used to describe experimental spectroscopic methods. Spectral measurement devices are referred to as spectrometers, spectrophotometers, spectrographs or spectral analyzers. Daily observation of color can be related to spectroscopy. Neon lighting is a direct application of atomic spectroscopy. Neon and other noble gases have characteristic emission colors, and neon lamps use electricity to excite these emissions. Inks, dyes and paints include chemical compounds selected for their spectral characteristics in order to generate specific colors and hues. a commonly encountered molecular spectrum is nitrogen dioxide. Gaseous nitrogen dioxide has a characteristic that is a red absorption feature; this gives air polluted with nitrogen dioxide a reddish brown color. Rayleigh scattering is a spectroscopic scattering phenomenon that accounts for the color of the sky. Spectroscopy is used in physical and analytical chemistry because atoms and molecules have unique spectra. These spectra can be interpreted to derive information about the atoms and molecules, they can also be used to detect, identify and quantify chemicals. Spectroscopy is used in astronomy and remote sensing. Most research telescopes have spectrographs. The measured spectra are used to determine the chemical composition and physical properties of astronomical objects such as their temperture and velocity. Spectroscopy has many sub-disciplines, each with numerous implementations of specific spectroscopic techniques. The various implementations and techniques can be classified in several ways. Types of spectroscopy are distinguished by the type of radiative energy involved in the interaction. The spectrum is determined by measuring changes in the intensity or frequency of this energy in most applications. The types of radiative energy studied include: Electromagnetic radiation was the first sourcce of energy used for spectroscoic studies. Techniques that employ electromagnectic radiation are typically classified by the wavelength region of the spectrum and include microwave, terahertz, infrared, near infrared, visible and ultraviolet, x-ray and gamma spectroscopy. Particles can be a source of radiative energy and both electrons and neutrons are commonly used. For a particle, its kinetic energy determines its wavelength. Acoustic spectroscopy involves radiaed pressure waves. Mechanical methods can be employed to impart radiating energy, similar to acoustic waves, to solid materials.
