1. What is the meaning of each term in the grating equation, m(lambda) = dsin(thetam)?
2. If a grating has a ruling of 600 lines/mm, what is d, the spacing between slits in nm (nanometers)?
3. Calculate all of the possible values of thetam for light of wavelength 400 nm and of wavelength 700 nm using such a grating. (Remember that sin(thetam) is less than or equal to 1 and 1 nm = 10^-9 m).
