an experiment is set up in which a red laser with a wavelength of 656.2m is directed through a large, irregularly shaped piece of synthetic material. There is no way to measure the angle of refraction, but you see the laser turns blue inside the material so you use a specialized detector and find the blue light in the material has a wavelength of 468.0 nm. What is the velocity of the blue light in the material? What is the index of refraction of the synthetic material?
