Web1 dag geleden · The index of refraction describe how light travels through a medium. Where c is the speed of light in a vacuum (2.99 x 10 8 m/s) and v is the speed of light in the medium you are measuring in m/s. Going Further Try adding salt or sugar to the water in the container and perform the experiment again. What happens? 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. The fastest thing with …

Web★★ Tamang sagot sa tanong: If you travel in a speed light or much faster than can you timetravel with that sci-fi.. - studystoph.com 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. howard jones birmingham

The answer to this question is 'vacuum', where light can travel … Web14 okt. 2024 · If the medium is denser speed of light will be slow because as the medium is denser there will be more atoms in Sq. Unit area so more atoms absorb more energy this reduces speed of light. If medium is rarer then there are less atoms In Sq. Unit area thus atoms will absorb less energy as compared to denser medium. how many jews fought in ww2
