Energy needed to remove an electron
When using the equation E0= Erad-K=hf-1/2mv^2 to find, are we only using the right side of the equation starting at hf? I'm unsure as to how I would apply the left part of the equation?

Re: Energy needed to remove an electron
I believe Erad is equal to hf and K is equal to 1/2mv^2, the left part just tells you the name of what you are calculating: Erad for energy of incoming photon(radiation) and K for kinetic energy.

Re: Energy needed to remove an electron
HI! When solving a problem regarding the photoelectic effect, we know that . represents the energy of the photon. is the energy required to remove an electron (threshold energy). is kinetic energy. Knowing any two of the three values in this equation will help you solve for the third. I hope this helps!

I conceptualize it using this equation:
