Okay, So this question now we're moving on from not crystallography, but just the Compton effect. And so we know that razor scattered at an angle of 55 degrees with respect to the direction of the incident beam Sillas Caller 5 55 degrees. And we want to get huh? The wavelength of the scattered the wavelength shipped of the X ray so we can use the formula. The Delta Lambda is equal to age over M. C. Um, Times one minus the co sign of 55 of the angle. Oops. And M is the mass of the electron. And so I'm gonna go ahead and plug all of this in my computer. Ages, of course. Planck's constant So 6.626 kinds 10 to the minus 34. Good righted by 9.11% of the minus 31 times 2.998 times 10 to the A. I am too one minus a co sign of 55. And so we can see that the wavelength of this 1.3 times 10 to the minus 12
