hi. can someone explain to me the difference between stopping potential, electron volts and work functions? my test is next Thursday! help!

Question

anonymous · Answer

studying photoelectric effect ?

anonymous · Answer

yes

anonymous · Answer

the minimum potential that must be applied to stop the electrons from being ejected from the surface is stopping potential

anonymous · Answer

electron volt is a unit

anonymous · Answer

the work function (sometimes spelled workfunction) is the minimum thermodynamic work (i.e. energy) needed to remove an electron from a solid to a point in the vacuum immediately outside the solid surface

anonymous · Answer

work funtions? and how do we derive the electron volts? by using which formula?

anonymous · Answer

can u explain what u mean ?

anonymous · Answer

and electron volt is a unit . 
 1 electron volt =1.60   into 10 ^-19 joules
