If we heat a substance (which has a high melting point), it … The main points of quantum theory are (i) Substances radiate or absorb energy discontinuously in the form of small packets or bundles of energy. Planck’s radiation law, a mathematical relationship formulated in 1900 by German physicist Max Planck to explain the spectral-energy distribution of radiation emitted by a blackbody (a hypothetical body that completely absorbs all radiant energy falling upon it, reaches some equilibrium temperature, and then reemits that energy as quickly as it absorbs it). He was trying to explain black body radiation, but could not explain with available theoretical tools at that time. They describe a universe consisting of bodies moving with clockwork predictability on a stage of absolute space and time. As progress in the science field was happening, Maxwell’s suggestion about the wave nature of electromagnetic radiation was helpful in explaining the phenomena such as interference, diffraction etc. i) Substances radiate or absorb energy discontinuously in the form of small packets or bundles of energy.
