Can an Electron Absorb Higher Frequency Photons to Transition Energy States?

AI Thread Summary
An electron can absorb higher frequency photons to transition between energy states, provided the energy is sufficient to overcome the energy difference between those states. If the absorbed photon has excess energy, the electron can be ejected from the atom, gaining kinetic energy equal to the difference. However, if the photon energy is below the ionization threshold, the electron is restricted to transitions within the atom's energy levels. This means that while higher frequency photons can facilitate transitions, they must meet specific energy criteria to effectively promote the electron. Understanding these energy dynamics is crucial in the context of the photoelectric effect.

Hi guys, for an electron to jump from a lower energy to a higher energy state, it must absorb photons that correspond to the difference of the these 2 enegry states. I am wondering if it is okey for an electron to absorb greater frequency of photons(greater energy) to make the transition and release the extra energy?

Yes... as long as it is enough energy to get right out from the atom. The electron gets ejected with a velocity that makes up the energy difference. But for less than the ionization energy, you are pretty much limited to the transitions from one level to another.
 
I was using the Smith chart to determine the input impedance of a transmission line that has a reflection from the load. One can do this if one knows the characteristic impedance Zo, the degree of mismatch of the load ZL and the length of the transmission line in wavelengths. However, my question is: Consider the input impedance of a wave which appears back at the source after reflection from the load and has traveled for some fraction of a wavelength. The impedance of this wave as it...
