The photoelectric effect occurs when (blank)
are emitted from metal when the metal is struck by light of certain frequencies.

Explanation:

When light shines on a shiny surface then there is emission of electrons or other free carriers. This effect is known as photoelectric effect.

The electrons which are emitted like this are known as photons.  

Therefore, we can conclude that the photoelectric effect occurs when electrons are emitted from metal when the metal is struck by light of certain frequencies.
