Rainbows from square drops. Suppose that, on some surreal world, raindrops had a square cross section and always tell with one face horizontal. Figure 33-56 shows such a falling drop, with a white beam of sunlight incident at θ = 70.0° at point P . The part of the light that enters the drop then travels to point A, where some of it refracts out into the air and the rest reflects. Thai reflected light then travels to point where again some of the light refracts out into the air and the rest reflects. What is the difference in the angles of the red light ( n = 1.331) and the blue light ( n = 1.343) that emerge at (a) point A and (b) point B ? (This angular difference in the light emerging at, say, point A would be the rainbow's angular width.) Figure 33-56 Problem 56.

Is work function of a metals surface related to surface energy and surface tension? What is the need to the work function component in the math of tension of metal surfaces that cannot be provided by existing equations of surface energy and surface tension? What are the key differences in each parameter and variables that allow for a differentiation of each function? What has a more significant meaning work function, surface tension or surface energy? Are there real differences and meaning? Please clarify and if possible provide examples . Does surface tension dependant on thickness of a metal or type of metal surface all having the same thickness? Clearly temperature has a profound change on surface tension what other variables besides temperature are key to surface tension. What if any is there a connection between crystal structure of the element and surface energy and tension? This is NOT a Assignment Question!!!
