An 18mm wide diffraction grating has rulings of 390 lines per mm. monochromatic light of 487 nm wavelength is incident generally on the grating.

1) At what angle away from the normal (where the central maximum of the diffraction pattern occurs) is the next intensity maximum?

2) What is the largest order, m, that exists for diffraction of this wavelength with this grating?

3) What is the largest angle from the normal at which an intensity maximum is formed?

4) What is the chromatic resolving power of this grating if it is utilized in second order (m=2) assuming that the full grating is illuminated?

5) What is the chromatic resolving power of this grating if it is utilized in second order assuming that the incident beam is only illuminating 2mm of the grating?
