Question

The de Broglie wavelength of an electron traveling at 7.0 x 107m/s is 1.0 x 10-11m. (Remember that me = 9.1 x 10-31kg and h = 6.63 x 10-34J·s) True or False.

Answer 1

I have an answer, but I'd really like to see if someone else comes up with the same thing.

Answer 2

I have an answer, what do you get when you solve the deBroglie wave equation? Is the calculated wavelength \(1*10^{-11}\)?

Answer 3

No, I got false, but everything else I've found has pointed at true, including your answer, so I'd say the answer must be true.

Answer 4

I got 4.22*10^-56
