Web1 feb. 2004 · This offers the potential for light to be controlled in one, two or three directions. If 1D or 2D periodicity is limited to the surface of an object, for example, the structure is commonly known as a diffraction grating. If 2D or 3D periodicity exists within the bulk of an object, however, it becomes what is now called a photonic crystal. http://labman.phys.utk.edu/phys222core/modules/m9/interference.html old obey clothing

A grating is said to be a transmission or … Webgratings with much finer periods than previously achieved. With these improved gratings, he was able to accurately measure the absorption lines in the solar spectrum, now known as the Fraunhofer lines [4]. Diffraction grating development, especially in the early years, was driven primarily by the demands of spectroscopists like Fraunhofer. my muscle chef similar
