Question

What will happen if ultraviolet light shines on metal

Answer 1

Answer:

if this doesnt help then im sorry...

Explanation:

When light is shined on certain metals, electrons may be knocked off the metal. This is called the photoelectric effect. By assuming that light is quantized, Einstein was able to explain the photoelectric effect. ... When UV light of a long wavelength and low frequency is shined on the zinc nothing happens.

Answer 2

Ah yay! Something I can answer.

Answer:

When UV light is shined upon certain metals something called the photoelectric effect occurs. The photoelectic effect is when electrons are discharged from the metal.

Explanation:

Metals contain many electrons and when the electrons are given enough energy they can leave the metal. The electrons that escape the metal are called photoelectrons; hence why this effect is called the photoelectic effect.
