The pictured graph shows the relationship between the maximum kinetic energy of electrons flying off the surface of a metal versus the frequency of light striking the metal surface as part of the photoelectric effect.

According to this graph, what will happen when light of frequency $ 7 \times 10^{14} Hz $ strikes the metal surface?


Electrons will be buried deeper within the surface.


Electrons will be emitted with negative kinetic energies.


A small number of electrons will be emitted with a small amounts of kinetic energy.


No electrons will be emitted.


The light will only knock loose electrons off the surface of the metal.
