CP2 Test 1 Questions & Answers 2024 If the index of refraction of a material is 1.5, this means that light travels - ANSWER-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 - ANSWER-3 times as fast in vacuum as it does in the material When light travels from air into plastic - ANSWER-its velocity and wavelength change, but its frequency does not change When light travels from air into diamond, - ANSWER- When light travels from air into quartz, - ANSWER-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 - ANSWER-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 - ANSWER-an odd number of half wavelengths A single-slit diffraction pattern is formed on a distant screen. Assuming the angles involved are small, by what factor will the width of the central bright spot on the screen changes if the slit width is halved? - ANSWER-it will double A single-slit diffraction pattern is formed on a distant screen. Assuming the angles involved are small, by what factor will the width of the central bright spot on the screen changes if the slit width is doubled? - ANSWER-it be cut in half
