A Littrow mount blaze grating has width 0.5 millimeters, and blaze wavelength 600nm. Abroadband laser centered at 600nm is incident on the grating at the blaze angle, 6g, relative tothe surface normal. It is observed that the grating resolves the wavelengths of 600nm and602nm in the first order based on the Rayleigh criterion. Determine the blaze angle 8g.

The expression for the angle, 2dsinθB=mλθB=sin-1mλ2dSubstitute the values, θB=sin-11600×10-920.5×10-3 =0.034∘
