SUMMARY
The speed of light in a medium can be calculated using the index of refraction (n) with the formula n = c/v, where c is the speed of light in a vacuum (approximately 300,000 km/s). For ethanol, with an index of refraction of n = 1.36, the speed of light can be determined by rearranging the formula to v = c/n. This results in a speed of light in ethanol of approximately 220,588 km/s. Understanding this relationship is crucial for accurately determining light speeds in various media.
