# What Effect Does the Light Have

SATPHY-QAKEGX

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?

A

Electrons will be buried deeper within the surface.

B

Electrons will be emitted with negative kinetic energies.

C

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

D

No electrons will be emitted.

E

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