Homework Equations
I'm not sure.
The Attempt at a Solution
And once again, I'm not too sure. Where do I start?
No, this equation will not work. Look back in your notes and try to figure out why.Well, I've got this:
I'm not sure if it's one to use.
E = hc/[tex]\lambda[/tex]
Aha! That is all I needed to know.No, this equation will not work. Look back in your notes and try to figure out why.
Look up "de Broglie wavelength."
