Can Bragg's spectrometer be used to determine wavelength of EM wave other than X-rays?

I have read that Bragg’s spectrometer is used to study crystals using X rays. It is also used to determine the wavelength of X-rays . My question is that can it be used to determine wavelength of any other EM wave?

Wikipedia says that " Bragg diffraction occurs when radiation, with a wavelength comparable to atomic spacings, is scattered in a specular fashion by the atoms of a crystalline system, and undergoes constructive interference."

Can this be the reason for using X rays?(Is it that the spacing between atoms is comparable to the wavelength of X-rays , so they are used?)
