Definition 1.A hot solid, liquid, or dense gas emits radiation at all wavelengths causing a continuous spectrum. - A spectrum is a band of colors separated by their degree of refraction proportional to wavelength - Dark lines mean that certain wavelengths are being absorbed by something (Absorption) - Bright lines mean that certain wavelengths are being emitted (Emission) - Continuous means nothing is being absorbed, you see every wavelength Gamma Ray. Fourier analysis converts a signal from its original domain (often time or space) to a representation in the frequency domain and vice versa. Made by electrons jumping up farther from the nucleus of the atom. This quantum behavior of atoms could explain the drop-off of a continuous spectrum's shape at the short wavelength end. It is extremely helpful when interpreting astronomical data because it can ignore any variation which can muddle the true measurements of something, such as spectral line data. Sign up here.

Temperature scale used in astronomy: Term. Any solid, liquid and dense (thick) gas at a temperature above absolute zero will produce a thermal spectrum. Note the trends: bluer light has shorter, higher f, and more energy.Redder light has longer, lower f, and less energy.. At the beginning of the 20th century Max Planck (lived 1858--1947) suggested that atoms can absorb and emit energy in only discrete chunks (called quanta).
