1 Bragg Diffraction 2dsinq = nl Bragg Equation
Light waves incident on a crystal (at grazing angle q) reflect from multiple atomic planes The path difference of the reflected waves is 2dsinq , where d is the spacing between planes Constructive interference occurs when the path difference equals an integer multiple of the incident wavelength … Bragg Equation 2dsinq = nl
