Homework Statement
Q. How much energy will it take to remove only one electron on the surface of Nickle? If you hit the surface of Nickel with a photon that has a wavelength of 90 nm, what will the wavelength of that ejected electron be?
Homework Equations
KE= 1/2 MV^2
[tex]\lambda[/tex]=h/mv
ET=IE+KE
The Attempt at a Solution
I have attempted to change the Et=90nm into velocity and got V=8087.240m/s
Got the IE of Ni which is IE=1.257J
But I am stuck there i have no idea how to get back in the problem to solve for KE then turn that back into nm. Any help will be appreciated. Thnks
