28. When a narrow beam of white light is normally incident on a diffraction grating, you observe that the light to either side forms a complete spectrum from blue to red. Then you see that the spectrum repeats, but this time you see blue, then green, yellow, and purple, green, etc. The purple seems to be a mixture of red and blue light together. As you work through the problem, you conclude that blue light of wavelength 420 nm has...
