Whose radiation can a black body absorb?
A black body can absorb radiation from all wavelengths. As a theoretical concept, a black body absorbs all radiation incident upon it, regardless of the wavelength. This characteristic makes it an ideal absorber and emitter of radiation, which forms the basis of many principles in thermodynamics and electromagnetic theory.

A black body can absorb radiation from all wavelengths across the electromagnetic spectrum. According to theoretical physics, a black body is an idealized object that absorbs all radiation incident upon it and emits radiation according to its temperature. This characteristic holds true for radiation of all wavelengths, from the shortest gamma rays to the longest radio waves.
The concept of a black body is crucial in understanding various principles in thermodynamics, quantum mechanics, and electromagnetic theory. It serves as a standard reference for the study of radiation and is essential in fields such as astrophysics, where it helps in modeling the radiation emitted by stars and other celestial bodies.
Therefore, the correct answer is [D] All wavelengths, as a black body is capable of absorbing radiation from across the entire electromagnetic spectrum, without any preference for specific wavelengths.
