WebA diffraction grating is the tool of choice for separating the colors in incident light. The condition for maximum intensity is the same as that for a double slit. However, angular separation of the maxima is generally much greater because the slit spacing is so small for a diffraction grating. the slit separation is d = micrometers = x10^ m ...

WebIn contrast to normal gratings, echelles are ruled at 30–300 grooves per millimeter by ion bombardment, and are frequently in the range of 30–120 orders. The grating consists of saw-like grooves varying in height and 6–13 μm in depth. The echelle grating is designed to separate one order of diffraction from another. Webd λ = λ 1 − λ 2 = 5896 − 5890 = 6 A o. λ 2 < λ 1 R.P for λ 1 will be less than λ 2. Hence, we calculate N for λ 1 as the same will resolve for λ 2. λ 1 d λ = m N. N = 5890 …
