An expression is derived for the Bragg angle of synthetic multilayer x-ray reflectors. It displays the explicit dependences on not only the wavelength of the radiation and the period of the multilayer, but also on the ratio of the thicknesses of the two layers comprising one period. Absorptive dependence is also taken into account.
