Let's consider a case where we have a proton with a wavelength of two nanometers, and we want to find the velocity, that proton.
00:14
So we can use our typical equation, which is the wavelength, lambda, is equal to planck's constant divided by mass times volume.
00:29
Solving for velocity, we will get...
00:35
Velocity is equal to planx constant over the mass times the wavelength.
00:46
So our wavelength in this case is two nanometers.
00:50
So let's convert that over to meters.
00:54
So to convert that to meters, you would do two times one times 10 to the negative nine, which is just going to give you two times 10 to the negative nine.
01:12
So that is in meters now...
