How fast does light travel through air
WebBut nothing ever travels faster than c. 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. Web15 mrt. 2024 · When travelling through air, the speed of sound is about 330 metres per second (m/s).
