I am afraid that I know not much information about the questions. Sadly, I am enrolled in a poorly written Physics class online. I am not looking for the answers, but just how to go about finding them. The book never explained what eV was, but gave be basic equations like: E = hf, KE = hf + work function, and wavelength = h/mv

h is always Planck's constant.

It would be great to know the equations, units, etc. I can use. Because I am confused with Jules and Hz and nm and eV, etc.

Help? I am stuck. Thanks in advance!
