Is it better to take a shower in the morning or at night? In which medium does a sound wave travel faster: in air at 20°C and 1 atm or in air at 20°C and 5 atm? travel faster in warm water than in cold water. At room temperature, which is equivalent to 68 degrees, acoustic waves travel in water and air at speeds of 3,315 mph and 767 mph, respectively. And just like in air, warmer water has molecules that are moving quicker, and therefore warm water transmits sound faster than cold water. The speed of a sound wave depends upon the medium through which it travels. the fact that sound travels faster in warm water than in cold water. In fact, sound waves travel over 17 times faster through steel than through air. Refraction is the bending of waves when they enter a medium where their speed is different.

A great example we can imagine is touching the surface of water and watching the ripples spread, and then touching the surface of jell-o and seeing how the `ripples" spread -- the wave that our hand makes in the water is very different than in jell-o because one is fully liquid and the other . Humidity lowers the density of air (so much for humid air feeling heavy ! Raising the temperature of a cubic centimetre of water by 1°C takes more than 3200 times as much energy than you'd need to heat the same volume of air by the same amount. ( Log Out / Refraction is not so important a phenomenon with sound as it is with light where it is responsible for image formation by lenses, the eye, cameras, etc.But bending of sound waves does occur and is an interesting phenomena in sound. Gateshead-based science presenter Steve Mould created the the test to see if they can hear the difference between hot and cold water. They also travel faster on hotter days as the molecules bump . For starters, sound travels in dry air at a speed of around 343 m/s (767 mph). has a higher density. In case you're curious just how quickly sound travels through different mediums, here are a few of the different materials and how fast sound moves through them: Rubber — 60 m/s. That inversion also traps the sound waves near the ground and allows them to travel horizontally much farther than usual. In air, the speed of sound is related to air temperature T by vw = (331m/s)√ T 273K v w = ( 331 m/s) T 273 K . The speed of sound . Water has a very high volumetric heat capacity.
