WebThe speed of light is slower in material than it is in a vacuum. The "index of refraction" of a material is the ratio between "c" and the speed of light in that material. For example, glass has an index of refraction of about 1.5, meaning that light travels at only about 2/3 the speed it travels in a vacuum. Dr. Eric Christian.
