Refractometry is an analytical method based on the difference between the speed of light as it travels through a substance (v) and its speed in a vacuum (c). In the procedure, light of a known wavelength passes through a fixed thickness of the substance at a known temperature. The index of refraction equals c/v. Using yellow light (2 = 589 nm) at 20°C, for example, the index of refraction of water is 1.33, and that of diamond is 2.42. Enter your answers in scientific notation.
