Best ResponseYou've already chosen the best response.2the speed v of light in a medium whose refractive index is n, is given by the subsequent formula: \[\Large v = \frac{c}{n}\] where c is the light speed in vacuum Now the refractive index of air is about 1. Next the refractive index of water is greater than 1, so we can write: \[\Large {v_{WATER}} = \frac{c}{{{n_{WATER}}}}\] \[\Large {n_{WATER}} > 1\] what can you conclude?

Best ResponseYou've already chosen the best response.2yes since: being \[\Large {n_{WATER}} > 1\] then: \[\Large {v_{WATER}} = \frac{c}{{{n_{WATER}}}} < c\]
