Final answer:
The total emission from a blackbody is known as blackbody radiation. The total emission, across all wavelengths, from a blackbody is known as a) Blackbody radiation.
Step-by-step explanation:
The total emission, across all wavelengths, from a blackbody is known as a) Blackbody radiation. This refers to the radiation emitted by a blackbody at a given temperature, which covers all wavelengths of the electromagnetic spectrum. The correct answer is a) Blackbody radiation. Blackbody radiation refers to the total electromagnetic radiation emitted by a perfect absorber (or emitter) of radiation at all wavelengths. It is characterized by the temperature of the object, and according to Planck's law, the intensity of blackbody radiation varies with wavelength. Stefan's law and Wien's Law are related concepts but describe different aspects. Stefan's law defines the total power radiated by a blackbody, while Wien's Law relates the temperature of a blackbody to the peak wavelength of its emitted radiation. Planck's constant is a fundamental constant in quantum mechanics, unrelated to total blackbody emission.
