The power of this phenomenon for a particular order is optimized in a technique known as "blazing," which generally minimizes its zeroth order form.
The power of this phenomenon for a particular order is optimized in a technique known as "blazing," which generally minimizes its zeroth order form. This phenomenon can be used in an experiment in combination with the Scherrer equation to determine the size of particles of a powder. It is common to measure the thickness of a strand of hair using this phenomenon and Babinet's principle. James Gregory theorized a device consisting of periodic (*) "gratings" which would induce this phenomenon. The formula "two times distance times sine of the scattering angle is equal to n times wavelength" describes this phenomenon; that equation, Bragg's law, describes this phenomenon's use in crystallography. For 10 points, name this phenomenon in which a light wave bends around an obstacle.
