Speed of light from permittivity
WebAug 9, 2024 · In glass, light travels about 2/3 the speed of a vacuum (or air), which is why camera lenses and spectacles work so well to bend the light. The amount light is slowed is determined by the refractive index of the material. WebBy now you should have memorized the speed of light in a free space ("c"), it's 2.9979E8 meters second, or about 186,000 miles per second, or as a rule of thumb, about one foot per nanosecond. This is the speed limit of the universe; no matter or …
