### 7th Edition, Quantum Theory, #1.B.15

I can't seem to figure our which equation to use in part a to calculate the wavelength of the electron. Does anyone know which equation is used?

Did they state velocity of the electron? If so you would use the equation h/mv=wavelength. M is the mass of electron.

With h/mv can't this also be expressed as h/p?
