In which medium does light travel the fastest
WebAnswer (1 of 34): Light travels fastest through a vacuum, such as outer space. In a vacuum, there are no particles to slow down or interfere with the travel of light, so it can … WebWhich medium slows the speed of light waves? Light waves travel much faster than sound waves. Light waves do not need a medium in which to travel but sound waves do. Explain that unlike sound, light waves travel fastest through a vacuum and air, and slower through other materials such as glass or water.

This means that light travels O 1.8 times… A: we know that refractive index n = … WebSolution Verified by Toppr Correct option is C) Speed of light in a medium of refractive index n is given by- v= nc Hence, for more v, n should be less. Among the given media. …
WebLight travels faster in a vacuum than in any other material because there are no particles to interrupt its flow. However, a vacuum is expensive to produce and difficult to maintain, so most materials that exist in nature can't be used for optical fibers. Web7 apr. 2024 · Light moves slowly in an optically denser medium. The refractive index is expressed as the ratio of the speed of light in a vacuum to the speed of light in that particular medium. So, if the speed of light in that particular medium is low, we would have a very high refractive index.
