Okay, so that's the problem nine, we want to take a note of the relationship between our wavelength and energy.
00:14
So if the wavelength is short, something like that, which you might find, if you're looking at your x -rays, so to speak, that's going to be high energy.
00:29
Okay, and then if we have a large wavelength, that's going to be low energy.
00:38
And i'm going to call that to measure a wavelength.
00:40
So you look for one full cycle, right? so once it gets to the same spot it was, see the apex of two points, or you can sort of look at the sort of lowest point of the two peaks, or you can even measure it from somewhere in the middle here.

You just want to get a full cycle in...
