A beam of `X`-rays impinges on a three-dimensional rectangular array whose periods are `a, b,` and `c`. The direction of the incident beam coincides with the direction along which the array period is equal to `a`. Find the directions to the diffraction maxima and the wavelength at which these maxima will be observed.
