Can someone explain how I would go about part b in problem 1B.7? I know how to do part a, but I can't figure out b.

Re: wavelike properties of an electron
I'm not really sure. I was just reading another post that asked a similar question and it sounded like the answer to your question is a yes. I would look at it though just to be sure.
