The speed of sound is dependent on pressure and the density of the medium.
velocity = square root of ( change in pressure / change in density )
In any given medium, both the pressure and density vary dramatically compared to air. So the effect is that the speed of sound is increased in materials that have a higher ratio of pressure to density.
Some examples are:
Air at 0 degrees C, absolute pressure 1 bar : 343 m/s
Water at 0 degrees C : 1435 m/s
Although the water is greater density than air, the pressure is much greater so
sound travels faster.
Diamond permits speed of sound at 12000 m/s
Dense solids, because the molecules are closer together.
Sound travels the fastest in nonporous solids like iron.
The speed of sound is greatest in the most dense medium.
The one that has the most density.
air
lead
In solids.
The speed of sound depends upon elasticity and inertia of the medium which in turn depend upon the temperature of the medium.That's why speed of sound depends upon the temperature of the medium.
Speed of sound increases with the increase in temperature of the medium .In fact the speed of sound is directly proportional to the square root of absolute temp. of the medium.
Speed of sound travels in gases (like air), in liquids, and in solids. In air at 20 °C speed of sound travels with c = 343 m/s.
Light will be transported without a medium. The speed of light is = 299 792 458 m/s. Sound need a medium to be transported. It's mostly air, where the temperature is important. The speed of air is 343 m/s at 20 degrees Celsius and 331.3 m/s at 0 degrees Celsius.
It depends on the substance the sound is traveling through. If the sound is traveling through air, it is usually about 800km/h. If it is traveling through water, the speed is about 4000km/h. If it is traveling through cosmos, its speed is 0km/h.
The speed of sound through the medium also increases.
The sound needs a medium to be transported. Without that medium (vacuum) there is no sound. The sound is blocked by air mulecules. The light does not need a medium.
Speed of sound depends on the density of the medium in which it travels. In air medium, speed of sound wave is approximately 330 m/s.
Speed of sound increases with the increase in temperature of the medium .In fact the speed of sound is directly proportional to the square root of absolute temp. of the medium.
actually medium has amain role in the speed of sound, In air the sound can move faster while comparing to any other medium like liquid ,solid
No it is not true. When the temperature of the medium increases the speed of sound in that medium increases.
Speed of sound in a medium depends only on the properties on the medium.
When the density of the medium increases, the speed of the sound wave increases.
The speed of light is the speed at which electromagnetic waves propagate through a medium. The speed of sound is the speed at which acoustic waves propagate through a medium. As the speed of sound relies on the medium moreso than the speed of light, sound propagates much slower than light.
because the density of the medium changes with temprature
It depends on the medium and the temperature. The warmer and thicker the medium the faster the sound travels.
The speed of sound depends upon elasticity and inertia of the medium which in turn depend upon the temperature of the medium.That's why speed of sound depends upon the temperature of the medium.
