Compute the all parts of given problem:

Problem: Electromagnetic waves of wavelength 0.173nm fall on a crystal surface. As the angle of incidence is gradually increased, starting at 0 o, you find that the first strong interference maximum occurs when the beam makes an angle of 22.0o with the surface of the crystal planes in the Bragg reflection.

Part I: What is the distance between the crystal planes?

Part II: At what other angles will interference maxima occur?
