Web31–1 The index of refraction. We have said before that light goes slower in water than in air, and slower, slightly, in air than in vacuum. This effect is described by the index of … Snell's law is used to determine the direction of light rays through refractive media with varying indices of refraction. The indices of refraction of the media, labeled , and so on, are used to represent the factor by which a light ray's speed decreases when traveling through a refractive medium, such as glass or water, as opposed to its velocity in a vacuum. WebVideo transcript. - In this video, we will find the expression for relative refractive index, and we will do that with the help of a numerical. So let's say we have been given this refractive index of glass, refractive index of water, and we are asked to find, what's the refractive index of glass with respect to water? Now before we began, let ... ship agency in philippines
