1. What is the angular separation of two spectral lines of wavelengths 440 nm and 388 nm formed in order m=2 with a 382 line/mm grating? Express the answer in degrees with two decimal places.

2. A diffraction grating has a grating spacing of 2,102 nm. If a light ray of a wavelength 549 nm is incident perpendicularly upon the grating, what angle (in degrees) will you see the second order diffraction spots at?

Express the answer with one decimal place.
