Wave Frequency

[Diana A 2L]

I have a conceptual question. For the frequency of a wave, is the frequency a total sum of all of the individual photons of that wave, or is the frequency the amount of energy present in each individual photon?

[Jesse H 2L]

I believe that the frequency is the amount of energy per photon according to the wave model.

[Tiffany Dong_4e]

I also believe it is the amount of energy per photon because photons are essentially discrete packets of energy in the form of waves.

I think it is the amount of energy in each individual photon because of the wave model.

Frequency is the total energy of a single photon in the wave model since as we have seen in the photoelectric experiments, there is a certain amount of energy needed to remove electrons from the surface of a metal, called the threshold energy. The energy of the photon must be equal to or greater than the threshold energy in order to eject an electron. Since increasing the intensity of the light did not work, and the only way to remove electrons was to increase the frequency of the light, increasing the frequency of the light changed the energy of the photons. One photon can only eject one electron, and the photon itself must have enough energy to eject it instead of the wave as a whole. So, in the case of the ejection of electrons, the frequency is the total energy of a single photon.

What is the relationship between the amplitude of a wave and the frequency? Or the relationship between amplitude and wavelength? What does amplitude tell us exactly?

I believe that amplitude tells you about the intensity of light. Hope this helps!

And frequency is measured in Hz

[Jacob Motawakel]

According to the wave model, frequency is the amount of energy in a single photon. This is proven in the experiment where increasing intensity of did not remove the electron, but increasing frequency of light did remove the electron. In this experiment it shows that frequency is the energy in a single photon because by increasing frequency, there was enough energy to reach or surpass the threshold energy.
