PART A: An x-ray beam with wavelength 0.270nm is directed at a crystal. As the angle of incidence increases, you observe the first strong interference maximum at an angle 66.0?. What is the spacing d between the planes of the crystal?
part B: Find the angle 2 at which you will find a second maximum.
