Or = sin-1(.642) = 39.96 400 Answer : c) niSin9i = nrSin0 = (0642), 4- When yellow light of wavelength 580 nm passes from air (n =1.00) into water (n=l .33), how does each of the following change, and what are their values in water? Technological applications based on the manipulations of light include lasers, holography, and fibre-optic telecommunications systems.. Rainbows White light separates into different colors (wavelengths) on entering the raindrop because red light is refracted by a lesser angle than blue light. Light carries energy and travels as a wave. Boardworks Ltd 2006 2004 Contents. Author: Created by beansontoast1.
