WebThis explains why sound travels faster through hotter air compared to colder air. The speed of sound at 20 degrees Celsius is about 343 meters per second, but the speed of sound at zero degrees Celsius is only about 331 meters per second. Remember, the only way to change the speed of sound is to change the properties of the medium it's ... Web8 nov. 2024 · The refractive index n for light in a particular medium is defined such that n ≡ speed of light in vacuum speed of light in medium = c vwave. The reason for this is that the speed of light in materials is typically 107 - 108 m/s, while the n for most materials is between one and five. The utility of the refractive index is that the values of ...

Web10 jan. 2024 · Light travels Faster in air, but slower in glass.In different materials, the speed of light slows down to less than c. That is because light refracts when it … 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, … WebCorrect 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. refractive index of water is the least. Hence, light travels fastest in water. Answer- (C) how to stop stomach pain from ibuprofen
