Problem

A diffraction grating separates three monochromatic visible beams of equal intensity. The first-order maxima appear at angles of 11∘11^{\circ}, 14∘14^{\circ}, and 17∘17^{\circ} from the central bright fringe. Without performing any calculations with the grating equation, match each angle to the most likely color among red, green, and violet.
