WebRupesh Routray. 263 1 2 7. One simple answer (and there are actual, deeper physics answers) is that the light interacts with the material, and those interactions are wavelength dependent. And, red light doesn't always travel faster than blue light - that is material dependent through those interactions mentioned above. – Jon Custer. WebLight is an electromagnetic wave. What that means is that it is an oscillating electric and magnetic field. An electric field, is what causes the attraction between a positive and a …

How Does Light Travel? Sciencing
WebJun 16, 2009 · Light travels fastest in a vacuum with an approximate speed of 3.0 * 108 ms-1. What stateof matter does light travel fastest through? Light travels fastest in a … WebFirst off, I don't understand why anything would travel slower in a vacuum. Vacuum = no friction = no electromagnetic interference = faster, for both matter AND energy. Light appears "slowed" in matter because the waves bounce off eachother causing interference, which has the net effect of making the light appear to move more slowly. So without ... WebJan 18, 2024 · It is often stated that the speed of light is constant and that nothing can travel faster than the speed of light. This isn't entirely accurate. The value of 299,792,458 meters per second (186,282 miles per second) is the speed of light in a vacuum. However, light actually slows down as it passes through different media. iit bombay 2020 cutoff
