The minimum frequency which is needed to eject an electrons from the surface of certain metals is called threshold frequency.
It is denoted by V0.
The value of threshold frequency is differs for different metals .
Light of frequency smaller than threshold frequency can't eject electrons no matter how the high light intensity is .
