What is the de Broglie wavelength of a 10 microKelvin Rb atom? A 5000K electron?
The Attempt at a Solution
I used the velocity equation to find the velocity relating to temperature and mass. Then, as p=mv, I calculated the wavelength of the Rb atom to be 86.4nm. I just want to make sure my line of thinking is correct and that I can use a similar process for the electron.
