What is the speed of light in water?
Understand the Problem
The question is asking for the speed of light when it travels through water, which is a physics concept. We need to consider the refractive index of water and how it affects the speed of light compared to its speed in a vacuum.
Answer
225,000 kilometers per second
The speed of light in water is approximately 225,000 kilometers per second
Answer for screen readers
The speed of light in water is approximately 225,000 kilometers per second
More Information
Light travels slower in water due to the refractive index of water, which is about 1.33. This means the speed of light in water is roughly 75% of its speed in a vacuum.
