Explanation:
Fluorescence can be defined as the phenomenon by which an object emits visible light when placed in front of ultraviolet light. In fluorescence, the absorbed light increases the energy band of the electrons, causing them to go into a more excited state. The electrons, before they release the absorbed energy in the form of light, lose a part of the energy due to the vibration of the molecules. When they return to their initial state, the electrons will emit light.
While microwaves are electromagnetic waves whose frequency is high, and are used for the transmission of high-speed telegraphic signals and for the communication of satellites and do not emit light.
