What are some of the most common materials that display the photoelectric effect?

the so-called alkali metals, the most used of all is potassium

Explanation:

The photoelectric effect is the expulsion of electrons from metals by effect of incident radiation.

To see this effect, materials with a small work function are needed, so the most used materials are the materials of group i of the periodic table, the so-called alkali metals, the most used of all is potassium

as technology advances, new experiments often expose problems in accepted theories. c
