Okay so, I was hoping someone out there might be able to assist me with a Mineralogy problem I have. The concept is based around X-Ray Diffraction.

The question:

Derive a diffraction equation from the illustration below that relates the reflection angle (theta) to the wavelength (lambda) and the d spacing (d). Show all of your work so that it is clear that you understand the physics and the math in this important derivation.

Here is a picture of the diagram given...sorry for the poor quality :)
