frequency and ejection of electrons

[Jina Kwon]

what is the relationship between frequency and the ejection of electrons ?

[AronCainBayot2K]

Based on the photoelectric effect, the ejection of electrons are determined by the frequency. If the light source has a short wavelength then it can eject electrons since the frequency would be high.

[Kurtis Liang 3I]

Frequency is directly proportional to the energy of the incoming light. If this energy exceeds the threshold energy for the surface, it will eject electrons.

[Charisse Vu 1H]

The photoelectric effect states that there is a certain amount of energy (threshold energy) needed for an electron to be ejected. The frequency of the incoming photon is what determines whether an electron can be ejected. If the photon has a high enough frequency so that its energy surpasses that of the threshold energy, an electron will be ejected.

I believe that an increase in frequency is directly related with an increase in the kinetic energy in electrons ejected from a surface due to the photoelectric effect. An increase in frequency does not increase the number of elecctrons emitted, however an increase in intensity will increase the number of electrons emitted if the threshold energy is met.

[Bradley Whitworth 4B]

If you know the frequency of light being directed towards a surface you can find the energy using E=hv (v is not actually the letter v it is a variable for frequency). Once the energy is known you can determine at what point that energy will overcome the work function of the surface at which point electrons will begin ejecting.

[Natalie C 1K]

increasing the frequency will increase the kinetic energy of ejected electrons. this is only true if the threshold energy is met

[Leyna Dang 2H]

According to the photoelectric effect, frequency is directly proportional to the ejection of electrons. However, these electrons will only be ejected if the threshold energy is met.
