Best ResponseYou've already chosen the best response.0X rays scattered from a crystal have a ﬁrstorder diffraction peak at θ = 15°. At what angle will the second and third order peaks appear? I have already found that taking arcsin(2sin15) and arcsin(3sin15) get the correct answer. I just have no idea why!
