A laser beam has a velocity in vacuum of c 3 x 108 ms a, Ask an Expert

Academics

A laser beam has a velocity in vacuum of c =3 x 10^8 m/s. A student runs an experiment in which a liquid is placed in a tank of length L = 14.1 m. The time it takes for the beam to make it across the tank is timed to be t = 59 ns. Randomized Variables L=14 J m. t = 59 ns.

Part (a) Write an expression for the liquids index of refraction, n.

Part (b) Numerically, what is this index?
