For your science fair project you need to design a diffraction grating that will disperse the visible spectrum (400-700 nm) over 30.0 ^\circ in first order.
A. How many lines per millimeter does your grating need?
B. What is the first-order diffraction angle of light from a sodium lamp. lambda =589 nm
