what is the speed of light in water?

OpenStudy (jamesj):

By definition of the refractive index, n = speed of light in a vacuum / speed of light in medium. For water, n = 1.33. Given that, you can calculate the speed of light in water.

OpenStudy (jamesj):

Remember that the speed of light in a vacuum is \[ c = 3.00 \times 10^{10} \ \ m/s \]
