WebbThe quantity h is a constant now known as Planck's constant, in his honor. Although Planck was pleased he had resolved the blackbody radiation paradox, he was disturbed that to do so, he needed to assume the vibrating atoms required quantized energies, which he was unable to explain. The value of Planck's constant is very small, Webb26 juli 2024 · When infrared radiation is absorbed by an object it is heated and its temperature rises.
