X rays

  1. Jul 4, 2008 #1
    In order to study the structure of crystals, scientists normally use X-rays. Why do they use X-rays and not visible light?

    I'm thinking it has something to do with wavelengths, but I do not know why the difference of wavelenght matters.

    Visible light has a large wavelength, too large and clumsy to be helpful on the atomic scale.
    X-rays, on the other hand, have tiny crisp wavelengths, perfect for examining crystalline structures.
