Determine the refractive index of the plastic

Reference no: EM13550714

Using a fast-pulsed laser and electronic timing circuitry, you find that light travels a distance of 2.55m within a plastic rod in a time interval of 10.9ns. What is the refractive index of the plastic? Use 3.00×10^8 m/s for the speed of light in a vacuum.
