The more dense (thicker) the material, the faster sound can travel through it. Sound moves faster in solid objects than it does in air because the molecules are very close together in a solid and very far apart in a gas. The reason you hear things after you see them is because sound travels much more slowly than light.
According to NASA, sonic booms are "the thunder-like noise a person on the ground hears when an aircraft or other type of aerospace vehicle flies overhead faster than the speed of sound." "As objects travel through the air, the air.
Mar 20, 2006. "No," is what Albert Einstein would likely say if he was alive today—and he would be the man to ask, because scientists have been taking his word for it ever since the early 20th century. According to Einstein's theory of special relativity, published in 1905, nothing can exceed the speed of light. That speed.
The speed of light in a vacuum is 186,282 miles per second (299,792 kilometers per second), and in theory nothing can travel faster than light.
Feb 20, 2018. Sound is like light in some ways: it travels out from a definite source (such as an instrument or a noisy machine), just as light travels out from the Sun or a light bulb. That's why people who breathe in helium talk in funny voices: the sound waves their voices make travel faster—with higher frequency.
In a vacuum, all electromagnetic radiation (infra-red, light, ultraviolet, X-rays, gamma rays) travel at the speed of light, which is constant.
