WebA luminous solid, liquid, or dense gas emits light of all wavelengths. A low density, hot gas seen against a cooler background emits a BRIGHT LINE or EMISSION LINE spectrum. A low density, cool gas in front of a hotter source of a continuous spectrum creates a DARK LINE or ABSORPTION LINE spectrum. WebJul 31, 2024 · A spectral energy distribution (SED) is a graph of the energy emitted by an object as a function of different wavelengths. The graph at the right is a typical curve, called a blackbody curve. It shows that the amount of energy emitted by the object at all wavelengths varies with the temperature of the object.
