1. The problem statement, all variables and given/known data Do the maxima created by a diffraction grating all have the same intensity? Explain. 2. Relevant equations mλ = wsinθ (?) 3. The attempt at a solution According to the back of my textbook (Nelson Physics 12), the answer is no. I believe the answer may have to do with the fact that a diffraction grating also produces secondary maxima of a lesser intensity than the principal maxima, but I'm not sure. Overall, I would like to understand how to better explain this. Any help is appreciated!
