Threshold Energy

Postby Melissa_Aguirre1J » Sat Apr 21, 2018 11:50 pm

What would be considered the threshold energy?

How is the work function related to the threshold energy?

Threshold energy is the energy/work required to eject an electron. I believe that work function and threshold energy are the same thing.

Also important to note that the energy remaining after the threshold energy is reached is expressed as kinetic energy of the electron actually being ejected, such that KE = E(photon) - E(threshold)
