An object that absorbs all radiation falling on it, at all wavelengths, is called a black body. When a black body is at a uniform temperature, its emission has a characteristic frequency distribution that depends on the temperature. Its emission is called black-body radiation
hope it helps
Water is, indeed, an exception. Normally when temperature drops, material shrinks. Water doesn't, water expands instead.
D. frequency of the corresponding light wave
