14. Worked example 3.1
Question. A diffraction grating has a ruled area that is cm wide, has grooves per mm and is blazed at an angle of 45.00°.
(a)    What is the wavelength of radiation diffracted at the blaze angle in the first, fourth and ninth orders?
(b)    What is the resolving power in these orders?
(c)    What is the resolution in terms of wavelength (nm), wavenumber (cm-1) and frequency (GHz) in the ninth order at 300 nm?
