I was looking for a frequency by calculating the wavelength, and I found the answer. However, I have no idea where I came up with one of the values!(adsbygoogle = window.adsbygoogle || []).push({});

my notes say:

wavelength = Planck Constant / (proton mass* velocity)

My values:

1.9078e-21 m = 6.63e-034 / (2.81e-8* 1.236e-5)

The velocity is equal to longest wavelength of the electromagnetic radiation emitted by the hydrogen atom undergoing a transition from the n = 7 level, shown in m/s. The Planck Constant is what it is.

But what was I thinking when I came up with the mass of a proton as 2.81e-8?! Here's the thing THE NUMBER WORKS. And when I came up with that one, I was like, "Okay, we'll just call that 'proton mass' for now and see what happens."

I'm sure it had something to do with charge and/or angular momentum.

Does anyone know what I was thinking?! Thanks!
