SOLVED:A reflection grating is required that can resolve wavelengths as close as 0.02 A in second order for the spectral region around 350 nm. The grating is to be installed in an instrument where light from the entrance slit is incident normally on the grating. If the manufacturer provides rulings over a 10 -cm grating width, determine (a) the minimum number of grooves/cm required; (b) the optimum blaze angle for work in this region; (c) the angle of diffraction where irradiance is maximum (sho

SOLVED:A plane reflection grating with 300 grooves/mm is blazed at 10^∘. a. At what wavelength in first order does the grating direct the maximum energy when used with the incident light normal to the groove faces? b. What is the plate factor in first order when the grating is used in a Czerny-Turner mounting with mirrors of 3.4-m radius of curvature?
