Sound waves travel fastest in solids because the particles are closer together and have strong bonds. Sound travels at 340 m/s in air, 1560 m/s in water and 5000 m/s in steel. This is a lot slower than the speed of light, which is 3 x 108m/s (300,000,000 m/s). This explain...
Sound is a disturbance caused by variations in pressure that travels as longitudinal waves through a medium such as air or water, disturbing molecules along the way. The study of sound is known as acoustics. Humans detect sound waves through their ears. When a twig breaks, it pushes the air...

Speed of Sound Formula Reviewed by: Gaurang Shah Sound is a vibration or noise which travels through any medium. It travels in energy waves from one molecule to another, and when it enters a person's ear, it can be easily perceived. When an object vibrates, for example, it passes energ...
We are constantly surrounded by air, so it’s natural that the sound we hear reaches our ears aftertravelingthrough air. For starters, sound travels in dry air at a speed of around 343 m/s (767 mph). I should also remind you that sound travels theslowestin air; it travels much faster...
