Calculate the speed of light in glass. The index of refraction of a medium is. Now we can use numbers to calculate v the speed of light in the glass v 30 x 10 8 ms 16 v 188 x 10 8 ms.
The speed of light in vacuum commonly denoted c is a universal physical constant important in many areas of physicsIts exact value is defined as 299 792 458 metres per second approximately 300 000 kms or 186 000 mis.
Air has an index of 10 water is 13 and many types of glass are around 15. C299792458 ms1 And that is absolutely 100. Use the Snells Law equations url below. Place the point light source a known distance from the surface of the object.
