## Problem of the Week: Basic Sciences Problems: Light and Wave Propagation

Electronic distance measurements (EDMs) rely on an accurate estimation of the speed of light through the atmosphere. The ratio between the speed of light in a vacuum and the speed of light in the atmosphere is known as the refractive index of air. Derivation of the correct refractive index of air depends on knowing the wavelength under consideration, the temperature, the humidity, and which of the following?

A. Absorption
B. Atmospheric Pressure
C. Wind Speed
D. Emissivity
