ELECTROMAGNETIC SPEC

TermDefinition
ELECTROMAGNETIC RADIATION a kind of radiation including visible light, radio waves, gamma rays, and X-rays, in which electric and magnetic fields vary simultaneously.
Electromagnetic Spectrum the range of wavelengths or frequencies over which electromagnetic radiation extends.
Wavelength the distance between successive crests of a wave, especially points in a sound wave or electromagnetic wave.
Frequency he rate at which a vibration occurs that constitutes a wave, either in a material (as in sound waves), or in an electromagnetic field (as in radio waves and light), usually measured per second.
Photoelectric Effect The photoelectric effect refers to the emission, or ejection, of electrons from the surface of, generally, a metal in response to incident light
Quantum a discrete quantity of energy proportional in magnitude to the frequency of the radiation it represents.
Photon a particle representing a quantum of light or other electromagnetic radiation. A photon carries energy proportional to the radiation frequency but has zero rest mass.
Ground State the lowest energy state of an atom or other particle.
Excited State excited state can commonly take the form of the electron jumping from its original energy level or orbital, also known as the ground state, to an empty orbital of a higher energy shell that is further away from the nucleus.
Line Emission Spectrum When an electric current passes through a gas, it gives energy to the gas. This energy is then given out as light of several definite wavelengths (colours). This is called a line emission spectrum.
Continuous Spectrum an emission spectrum that consists of a continuum of wavelengths.
