Coating of a metal surface.
Explanation:
If a metal surface is coated, this can result in stopping of the emission of electrons from its surface. At certain frequencies, electrons can be ejected from the surface of metals.
- Albert Einstein proposed the photoelectric effect.
- The effect simply implies that there is an emission of electrons and other particles when light heat the surface of a metal.
- At the right frequency, light can have enough energy to eject electrons from metallic bodies.
- This highly applicable in photoelectric cells.
- When a metal surface becomes coated emission of electrons can be stopped.
