Light Intensity

how does the energy per photon affect the ejection of electrons?

[Samuel Mushinski 2G]

Hello! It is important to remember that one photon will always interact with one electron. The higher the energy of the photon, the more likely an electron will be ejected. If the photon has enough energy, then the higher the energy of the photon, the more kinetic energy the electron will have when ejected!

[Sanjana Narayanan 2J]

In order for a photon to eject an electron, it must have at least the minimum amount of energy that would be needed to remove that electron, so the main relationship between the energy of a photon and the ejection of electrons is whether the photon is of a high enough energy to eject the electron.

Hi! Keep in mind that the frequency of the wavelength matters more than the intensity. If the frequency does not reach a certain threshold, then no electrons will be ejected at all.
