Can someone help me with a simple bragg reflection question?
X rays scattered from a crystal have a ﬁrst-order 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!
the only formula my textbook gives is \[n \lambda=2dsin \theta \] It doesn't say what n is other that "an integer"
never mind, wikipedia explained it. super easy once I realized what n was.
