Photons are massless, so they always move at the speed of … Ver mais The word quanta (singular quantum, Latin for how much) was used before 1900 to mean particles or amounts of different quantities, including electricity. In 1900, the German physicist Max Planck was studying black-body radiation, … Ver mais In most theories up to the eighteenth century, light was pictured as being made up of particles. Since particle models cannot easily account for the refraction, diffraction Ver mais In 1924, Satyendra Nath Bose derived Planck's law of black-body radiation without using any electromagnetism, but rather by using a modification of coarse-grained counting of phase space. Einstein showed that this modification is equivalent to assuming that … Ver mais Quantization of the electromagnetic field In 1910, Peter Debye derived Planck's law of black-body radiation from a relatively simple assumption.
