## Homework Statement

Do the maxima created by a diffraction grating all have the same intensity? Explain.

## Homework Equations

mλ = wsinθ (?)

## 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!
