Homework Statement


Hi

I am told that 1 (E)1/2 = 9.045Å-1, where E is the energy in meV. How do I find out what 1 meV is in Å from that? All I can get is the correspondence between meV and Å-2, not meV and Å.

What does the Å represent?
Do the 1 and 9.045 have units?
Maybe your job is just to solve the equation for Å, and put in 1 MeV for E. Not a clear question in my opinion - if you have posted all of it. Normally the 1 MeV would be changed into standard units of energy (Joules) but I don't know what you should do in this case.
