Which statement explains how the photoelectric effect influenced the way physicists view electromagnetic radiation?(1 point)
Responses

Physicists initially considered electromagnetic radiation using the particle model. The photoelectric effect brought about the wave model.

Why was the wave model of electromagnetic radiation unsuitable for describing the photoelectric effect?(1 point)
Responses

because it predicted that increasing the intensity of the radiation would release fewer electrons
because it predicted that increasing the intensity of the radiation would release fewer electrons

because it predicted that electrons would be able to store energy
because it predicted that electrons would be able to store energy

because it predicted that electrons would not be able to store energy
because it predicted that electrons would not be able to store energy

because it predicted that increasing the intensity of the radiation would lower the kinetic energy of the electrons

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.

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.
The energy of the electrons that are emitted by the material all have the same frequency.

The frequency of the electrons emitted by the material decreases as the energy increases.
