1. What is the angular separation of two spectral lines of wavelengths 439 nm and 395 nm formed in order m=2 with a 367 line/mm grating? Express the answer in degrees with two decimal places.

2. A diffraction grating has a grating spacing of 2,130 nm. If a light ray of a wavelength 591 nm is incident perpendicularly upon the grating, what angle (in degrees) will you see the second order diffraction spots at?

3. A diffraction grating has a grating spacing of 2,045 nm. If a light ray of a wavelength 471 nm is incident perpendicularly upon the grating, what angle (in degrees) will you see the first order diffraction spots at?
