Kinetic Energy

[AndrewNguyen_2H]

I'm looking at a quizlet with this true or false
t/f higher frequency light always emits electrons with higher kinetic energies

I think it's true but the answer says it's false.
Is this a typo or am I missing something?

[Sofia Lucido 3L]

I think it might be false just because even if the light has a higher frequency, it might not have enough energy to match the threshold energy?

[Sofia Lucido 3L]

To add to what I said before, if you make the assumption that the energy of the light matches the threshold energy then, yes I think it's true that increasing the frequency of the light would emit electrons with higher kinetic energy. Perhaps this question does not want you to make that assumption.

[Charlie Russell 2L]

True because higher frequency has a direct relationship with kinetic energy, after threshold is met!

[Kayla Law 2D]

I think it's false because you're not supposed to assume that the energy of the light is already equal to or greater than the work function. So even if the frequency increases, if the energy is still below that of the work function, no electrons will be ejected. Hope this helps! :)

[Chelsea_Guzman_3C]

A higher frequency light would emit electrons with higher kinetic energy if and only if the frequency is already high enough for an electron to be ejected. If not, you can't make that assumption, therefore it would be false.

[Sharon Kim 2A]

I was thinking that if the light has a higher frequency, the energy emitted would be the same as long as the the energy (frequency) is reaching the energy threshold. The same energy would be emitted that was initially absorbed.

Id say its true because with the equation E(photon)-work function=Kinetic energy, the higher the frequency, the larger the energy of photon, so the larger the kinetic energy.

[Haochen He 3L]

According to the equation E(photon)-work function=Kinetic energy, the work funtion is a constant. So the higher frequency, the larger energy of Photo, and thus the larger kinetic energy.

[Yijia_Yang_3A]

true if the question is asked under the same condition, ie. same surface.

[Chinmayi Mutyala 3H]

I feel like that should be true since higher frequency means more energy but maybe it's because the frequency isn't enough to eject the electron. I'm not sure if there were any additional details given in the question.
