Question
bstances at 20 sc for light with a a vacuum. Through which substance will light with a vacuum 1. The table lists the index of refraction for various su wavelength of 589 nm in avelength of greatest speed? 391 9on9TWS 589 nm travel with the glo ESSS 2YH9 Substange 1.458 1.362 fused quartz ethyl alcobol 1.520 crown glass carbon tetrachloride 1.461 1.544 A) fused quartz B) crown glass ethyl alcohol ) carbon tetrachloride E) crystalline quartz 2. The bending of light as it moves from one medium to another with differing indices of refraction is due to a change in what property of the light? A) amplitude B) period C) frequency D speed E) color 3. White light enters a glass prism, but the color components of the light are observed to emerge from the prism. Which one of the following statements best explains this observation? A) The separation of white light into its color components is due to the increase in the speed of light within the glass. B) Some of the color components of the white light are absorbed by the glass and only the remaining components are observed. C The index of refraction of the glass depends on the wavelength, so the color components are refracted at different angles. D) Only some of the color components are refracted by the glass; and these are the ones that are observed. E) White light is separated into its color components by total internal reflection within the prism.Explanation / Answer
1.ethyl alcohol, since its refractive index is lower than the others.
2. Speed, light travels in different speed in different medium.
3. The index of refraction depends on the wavelength of the light.
