    Problem with wave optics - diffraction grating?

    Homework Statement For your science fair project, you need to design a diffraction grating that will disperse the visible spectrum (400-700nm) over 30 degrees in first order. How many lines per mm does your grating need?Homework Equations sin(Θ) = mλ/d y = Ltan(Θ) I'm pretty sure the only...
