| Black body radiation | Aerospace | 1: Light or other electromagnetic radiation emitted due to heat by a solid, liquid or dense gas, with no color of its own (hence "black"). Distinguished by a continuous distribution of spectral color, with its peak of emission shifting towards shorter wavelengths as the temperature increases, e.g. infra-red for a warm hand, red for a hot iron bar, yellow for the glowing filament in a light bulb. (references) | |
| 2: Radiation emitted by a hypothetical perfect radiator. The spectrum is continuous, and the wavelength of maximum emission depends on the body's temperature. (references) | |||
