What happens to the energy if the light source's energy does not pass the energy threshold?
Thank you in advance :)

Re: Question about Energy Threshold
I just want to make sure I'm understanding your question :) are you asking what happens if the photon doesn't have enough energy to remove the electron?
Re: Question about Energy Threshold
Yeah! I'm assuming it's absorbed or something just because energy can't be destroyed. But I'm curious to know how the energy is converted.

Re: Question about Energy Threshold
The energy threshold won’t be enough to create the photoelectric effect but the energy will be conserved. The energy might be reabsorbed or refracted.

Re: Question about Energy Threshold
If the light source's energy does not pass the energy threshold the electrons won't be ejected since E(Photon) is less than the threshold energy. If the E(Photon) and the threshold energy are equal then the electron will be released but will have no kinetic energy.

Re: Question about Energy Threshold
The electron only jumps orbitals if the energy of the photon reaches the energy threshold(exactly how much energy is required to excite the electron), or is greater than the energy threshold. Increasing the intensity or wavelength of light will not result in the electron being excited because these elements alter the number of a photon hitting the electron, but not the energy of the photon itself. In order to excite the electron, the frequency in which the wave hits the electron would have to be increased. That being said, if the energy threshold is not reached the energy will not just disappear(first law of thermodynamic energy is always conserved), it may be absorbed by the electron or refracted.

Re: Question about Energy Threshold
If there is not enough energy to bounce the electron off the metal surface, then the photoelectric effect will not happen.

Re: Question about Energy Threshold
If the energy isn't enough to pass the threshold, the photon won't be able to remove electrons. The energy of the photon needs to be greater than the energy of the electron to remove it.
