Can sound travel through things other than air?
We know light can travel through a vacuum because sunlight has to race through the vacuum of space to reach us on Earth. Sound, however, cannot travel through a vacuum: it always has to have something to travel through (known as a medium), such as air, water, glass, or metal.
What does sound travel through faster than air?
Thus sound waves travel much faster in water than they do in air. In freshwater at room temperature, for example, sound travels about 4.3 times faster than it does in air at the same temperature.
Which item will sound travel fast through?
solids
The speed of sound depends on the medium in which it is transported. Sound travels fastest through solids, slower through liquids and slowest through gases.
How fast can sound travel through objects?
Sounds can travel at approximately 6000 metres per second in some solids and at a quarter of this speed in water. This is because the molecules of solids are more tightly packed together than in liquids and those in liquids are more tightly packed than in gases.
How fast does sound travel per second?
about 1,088 feet per second
This method is based on the fact that light travels much faster than sound through the atmosphere: Light travels at 186,291 miles per second (299,800 km/s), whereas the speed of sound is only about 1,088 feet per second (332 meters per second), depending on air temperature.
How far can sound waves travel?
The speed of the sound wave is 340 m/s. The distance can be found using d = v • t resulting in an answer of 25.5 m.
Will sound travel in a vacuum?
Sound does not travel at all in space. The vacuum of outer space has essentially zero air. Because sound is just vibrating air, space has no air to vibrate and therefore no sound.
What material does sound travel slowest?
gases
As a rule sound travels slowest through gases, faster through liquids, and fastest through solids.
Can sound pass through wood?
6 replies. “Sound travels faster in solids than in liquids or gases. The molecules of wood are much more compact than those of air. Hence the propagation of sound is more efficient in wood.”
How fast does sound travel if the air temperature is 20c?
about 343 metres per second
At 20 °C (68 °F), the speed of sound in air is about 343 metres per second (1,125 ft/s; 1,235 km/h; 767 mph; 667 kn), or one kilometre in 2.9 s or one mile in 4.7 s.
