Homework Statement
A surface ejects electrons when hit by green light but not when hit by yellow light. Will the number of photoelectrons ejected be changed if the surface is hit by indigo light?
A) yes B) No C) yes, if the indigo light is quite intense
Homework Equations
E = hv (h is plank's constant and v is frequency of photon)
The Attempt at a Solution
I know only one photon is necessary for ejection of a photo electron if it has energy more than the work function, so if the electrons are removed by green light, they must be removed by indigo light as well, but can the number of electrons released increase, supposing that indigo light can further eject electrons of deeper shells?
