An X-ray beam with = 151 incident on the surface of a crystal produced a maximum reflection at an angle of = 28.2.
Part A
Assuming , calculate the separation between layers of atoms in the crystal.

Confused on which formula to use to find this answer.

  • Chemistry. -

    wavelength = 2d*sin theta.
    solve for d although I'm confused by the 151 notation.

  • Chemistry. -

    Thank you so much! The 151 was the wavelength notation.
