de Broglie Relationship

Postby Victoria Luu - 1C » Sat Oct 06, 2018 2:55 pm

Looking at question 1.33 in the sixth edition, I was wondering how we know what mass to use. I understand that in h/mv, h is given and v is given as well, but what information do you use to know what m is?

The problem is asking about an electron and an electron's mass is a constant which is 9.11 x 10^-31.

I agree, it's asking for the mass of the electron.

Dr. Lavelle posted a file on his website that contains a whole list of constants that will be useful throughout the quarter--the mass of an electron in addition to everything he has/will cover should be on there.
