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...

14. Red and blue light from the sun are shining on a water drop. As the light refracts through the water, which of the following is true? A. Both colors of light bend the same amount because the speed of light is a constant. B. Red light bends more than blue light because it has the longer wavelength. C.
