Question:
In about A.D. 150, Claudius Ptolemy gave the following measured values for the angle of incidence θ1 and the angle of refraction θ2 for a light beam passing from air to water: Assuming these data are consistent with the law of refraction, use them to find the index of refraction of water. These data are interesting as perhaps the oldest recorded physical measurements.
