Chapter , Problem 49(choose chapter or problem)
Light of wavelength 600 nm is incident normally on a diffraction grating. Two adjacent maxima occur at angles given by sin u ! 0.2 and sin u ! 0.3. The fourth-order maxima are missing. (a) What is the separation between adjacent slits? (b) What is the smallest slit width this grating can have? For that slit width, what are the (c) largest, (d) second largest, and (e) third largest values of the order number m of the maxima produced by the grating?
