For the grating in Problem 7-13, calculate the wavelengths of first- and second order diffraction at reflective angles of (a) 25° and (b) 0°. Assume the incident angle is 45°.
Problem 7-13
Consider an infrared grating with 84.0 lines per millimeter and 15.0 mm of illuminated area. Calculate the first-order resolution (λ /∆ λ) of this grating. How far apart (in cm-1) must two lines centered at 1200 cm-1 be if they are to be resolved?
