The amount by which light slows in a given material is described by the index of refraction, n. The index of refraction of a material is defined by the speed of light in vacuum c divided by the speed of light through the material v : n = c / v. The index of refraction of some common materials are given below. Q. When atoms become packed super-closely . This is because what is called the index of refraction, (the ratio of the speed of light in a vacuum to the speed of light in a material), is increased for the slower moving waves (i.e. Light travels at 186,000 miles per second (300,000 kilometers per second) and can go from the Earth to the Moon in just over a second. Researchers from the University of Rochester have shown that it is possible to slow light as it travels through a certain type of crystal known as alexandrite. The light travels slowest in（ ）A. Visible light travels slowest in air and fastest in solid materials. 11. The refractive index of glass with respect to water will be: Light cannot travel through solids.

(A) The refractive index of glass is 1.5. Question Bank Solutions 24328. Light travels slowest in . Physicists Slow Speed of Light. Question 5. A ray of monochromatic light with a frequency of 5.09 × 1014 hertz is transmitted through four different media, listed below. 4. The indexes of refraction for diamond, air and glass are, respectively, 2.42, 1.00, and approximately 1.50, depending upon the composition of the glass. Blue travels the slowest of the visible colors and therefore makes the largest bend when it enters the glass prism. The higher the index of refraction is, the slower the speed of light is. Refraction and Total Internal Reflection Workshe Light travels (fastest, slowest) in media with a less optical density Light travels (fastest, slowest) in media with a lower index of refraction value.
