Which photoelectric effect observation supports the idea that the energy of a photon is proportional to its frequency?(1 point)
Responses
Only a single frequency will enable electrons to have the exact energy needed to escape the material.
Only a single frequency will enable electrons to have the exact energy needed to escape the material.
The frequency of the electrons emitted by the material decreases as the energy increases.
The frequency of the electrons emitted by the material decreases as the energy increases.
Electrons only have enough energy to escape the material when the light’s frequency is above a certain level.
Electrons only have enough energy to escape the material when the light’s frequency is above a certain level.
The energy of the electrons that are emitted by the material all have the same frequency.
