If the index of refraction of a material is 1.5, this means that light travels Ans: 1.5 times as fast in vacuum as it does in the material If the index of refraction of a material is 3, this means that light travels Ans: 3 times as fast in vacuum as it does in the material When light travels from air into plastic Ans: its velocity and wavelength change, but its frequency does not change When light travels from air into diamond, Ans: When light travels from air into quartz, Ans: its velocity and wavelength change, but its frequency does not change Two beams of coherent light start out at the same point in phase and travel different paths to arrive at point P. If the maximum constructive interference is to occur at point P, the two beams must travel paths that differ by Ans: a whole number of wavelengths Two beams of coherent light start out at the same point in phase and travel different paths to arrive at point P. If the maximum destructive interference is to occur at point P, the two beams must travel paths that differ by Ans: an odd number
