| e=hf
Kmax=hf-(work function)
f0=(work function)/h
E[emitted photon]=deltaE
lamba=(hc)/(Ej-Ei)
lambda=h/p
E=mc^2
you need to know nuclear decay and about electron volts too.
I figured it out today in about half an hour. i wish i could somehow give you the 5 steps book though. it saved me days of time i spent trying to learn it from the pr. |
