The given statement is correct. @John,

Electrons can only be knocked off the face of the metal when the frequency of incident light exceeds the threshold frequency (which is the minimum frequency required to knock off an electron).

So, The answer is True.

If the intensity of the light is more than threshold frequency then it is FALSE.
