(A) What kind of pattern of would you get if you shone monochromatic light on a diffraction grating? What pattern of light would you get if you shone white light on a diffraction grating?
My answer: With monochromatic light, you would get a pattern of alternating light and dark bands. With white light you'll get dispersion patterns -- bands of color arranged according to their frequency.
(B) Is it correct to say that the difference in patterns produced by the monochromatic and white light is caused by the fact that monochromatic light waves interfere with each other when they pass through a diffraction granting, while the rays of white light do not? Explain.
My answer: I'm pretty sure this statement is incorrect, but I can't quite put it into words. Does it have something to iridescence -- that is, light waves canceling out certain frequencies so we see component colors?
Am I on the right track at lest? Help would greatly be appreciated! :D
