Question

If I shine white light onto a diffraction grating at a distance of 1m, which wavelengths bend more, blues/violets or reds? (Remember, all five of these cases involve DIFfraction) Is this the same or opposite color bending order when compared to rainbow refraction? Where does the first band of red light hit the screen? (Draw a picture with all information you have so far) Where does the first band of violet light hit the screen?
