1. With light from a gaseous discharge tube incident normally on a grating with slit separation 2.23 μm, sharp maxima for a certain wavelength of light are produced at angles θ = -17.1° and +17.1°. Compute the wavelength of the light in nanometers.
2. I thought this would work... (wavelength) = d * sin θ, but it turns out its a bit more complicated, i can't find anything in my books to describe a situation like this or how to solve it.
