Question

fluorescence or phosphorescence of photoelectric effect is process
a) photochemical b) thermal
c) photophysical
d) photosensitised​

Answer 1

Answer:

d

Explanation:

as in case of cs and sodium electrons are highly energetic so they on little exposure get removed

Answer 2

a) photochemical

Explanation:

Fluorescence is a phenomena that results from the interaction of particular materials with specific light frequencies or energy. This easy-to-do, low-cost inquiry project brings the science of fluorescence to life — and clearly explains the photoelectric effect. Phosphorescence is light energy created by a certain sort of chemical reaction in which the reactants' surplus chemical energy is released as light energy. The emission of light by a substance that has absorbed light or other electromagnetic radiation is known as fluorescence.
