A diffraction grating is illuminated with yellow light. The diffraction pattern seen on a viewing screen consists of three yellow bright spots, one at the central maximum $)=(0$ and one on either side of it at $=+-50.$ Then the grating is simultaneously illuminated with red light. Where a red and a yellow spot overlap, an orange spot is produced. The new pattern consists of

an orange spot at $0,$ yellow spots at $+-50,$ and red spots closer in$.$

only orange spots at $0$ and $+-50.$

an orange spot at $0,$ yellow spots at $+-50,$ and red spots farther out.

only yellow spots at $0$ and $+-50.$

only red spots at $0$ and $+-50.$
