One photon one atom interaction

So after the energy of light surpasses the minimum energy needed to eject an electron, would increasing the energy of light (the frequency) increase the amount of electrons ejected at that point or would the amount of electrons ejected stay the same?

After the energy of light surpasses the minimum energy needed to eject an electron, increasing the energy of light (frequency) will increase the amount of electrons. in fact they will share a direct relationship where one million photons will eject one million electrons.

It would increase the kinetic energy of the electron -- with what remains of the initial energy after accounting for the work function

[Anika Chakrabarti 1A]

I don't think that increasing the frequency would increase the number of electrons ejected, since the number of electrons ejected still depends on the number of photons. But, if the energy of light is already greater than the minimum energy needed to eject an electron, then increasing the frequency would result in a greater kinetic energy of the electron.

[Jessica Tran_3K]

Increasing the energy of the light (more photons) would increase the amount of electrons ejected. Also, increasing intensity of the light would not increase amount of ejected electrons.

[Kavya Immadisetty 2B]

After the energy of the photon surpasses the minimum energy, increasing the frequency of the photon would not increase the number of electrons ejected because each photon interacts with 1 electron, not multiple. A higher frequency correlates to a higher kinetic energy of the ejected electron.
Increasing the intensity of the light (increasing the number of photons) would increase the number of electrons ejected.

[Alexa Hernandez 3k]

If the individual photon has already passed the energy threshold then theoretically the number of photons overall should equal the amount of ejected electrons.

[BryantChung_4B]

It would increase. Simply increasing the intensity (or number) of photons will not eject more electrons, but increasing the frequency will.

[Maya Gollamudi 1G]

Increasing the frequency of the light after the threshold energy has already been surpassed would increase the KE of the ejected electron. Increasing the intensity of the light (proportional to the number of photons) would increase the number of electrons ejected, because of the one photon-one electron interaction.

After increasing the frequency and the threshold of the electrons being met, in order to have more electrons being ejected you can then increase the intensity as it produces more photons at this energy, which increases photon, electron interactions. But remember that this will not change the amount of kinetic energy.

[Lauren Sanchez 3D]

So in order for the electron to be ejected, the frequency of the light has to be enough? The intensity does not matter if the frequency is not high enough right?

[Hussain Chharawalla 1G]

As you increase the frequency, you increase the energy of the photon. So yes, you must have a minimum frequency to eject an electron. Increasing the frequency further will just make the electron leave at a higher velocity.

As you increase the amplitude, you increase the amount of photons. Therefore, more electrons will be ejected.

Hope that helps

If the energy of each photon is enough to eject an electron, the increasing of the intensity of light is directly proportional to the amount of electrons ejected by the metal. However, if the wavelength is too long and each photon is not sufficient to satisfy the threshold, increasing intensity does not change the number of electrons ejected.

[kristi le 2F]

Increasing the energy (wavelength) of each individual photon would increase the kinetic energy of the electron emitted, given that the energy of the photon is above the work function.

[Caitlin Ciardelli 3E]

Each photon must have enough energy (at least the same energy as the work function) for an electron to be emitted. This energy relates to the wavelength. So, the shorter the wavelength, the higher the energy. Once threshold energy is reached in each short wavelength photon, increasing the frequency (amplitude of the wave) will result in more electrons being emitted. Hope this helps :)
