Detailed explanation-1: -Phosphorescence is a type of photoluminescence related to fluorescence. When exposed to light (radiation) of a shorter wavelength, a phosphorescent substance will glow, absorbing the light and reemitting it at a longer wavelength.
Detailed explanation-2: -Answer = A Explanation: Fluorescence is the emission of light by a substance that has absorbed light or other electromagnetic radiation. It is a form of luminescence.
Detailed explanation-3: -Phosphorescence is a phenomenon of delayed luminescence that corresponds to the radiative decay of the molecular triplet state.
Detailed explanation-4: -The phenomenon of having a continuous glow of a beam on the screen even after it is removed is called as phosphorescence. Explanation: Phosphorescence is luminescence that occurs when energy is supplied by electromagnetic radiation usually UV rays.
Detailed explanation-5: -Phosphorus, the light-emitting chemical element for which phosphors are named, emits light due to chemiluminescence, not phosphorescence.
