A parallel beam of light containing red (660 nm) and blue (470 nm) wavelengths goes from polystyrene to water, striking the surface between them at a 48° incident angle. What is the angle between the two colors in water?
------------- °
Coherent light with wavelength 546 nm passes through two very narrow slits, and the interference pattern is observed on a screen the distance of 3.00 {rm m} from the slits. The first-order bright fringe is a distance of 4.86 {rm mm} from the center o..
