the speed of sound depends on the material through which it's passing. it is greater in solids than in liquids or gases because the molecules in a solid are closer togather than in a liquid or gas.
Material Speed m/s
Air(0°C) 330
Water 1400
Concrete 5000
Steel 6000
"compression-type" sound will travel faster in solids than in liquids, and faster in liquids than in gases, because the solids are more difficult to compress than liquids, while liquids in turn are more difficult to compress than gases.

Can the speed of light be changed?
no. speed of light is always constant . as long as the light stays in the same medium. the speed is generally slightly different in different media.
What the media of speed of light?
The speed of light does not have any media.
Does light always travel at the same speed?
The speed of light is always the same as long as it's traveling through the same medium. But its speed is different in different media, and those are all less than its speed in vacuum.
What sounds travel through gas?
sound passes thro' different media which are generally solids, liquids and gases
What is it called when the speed and direction of light changes as it passes through different media?
its called refraction
What is constant in electromagnetic waves?
The speed is constant, at least for EM waves in a vacuum. The speed will still be approximately the same in other media, e.g. in glass. Different waves can have different frequences or wavelengths, but the speed will be the same.
What evidence is there that light travels at diff speeds?
Dispersion phenomenon establishes that light of different colours travel at different speed in a denser medium. Light traverses at different speed in different media is confirmed by the refraction phenomenon.
Why do sounds travel at different speed?
Never heard that. All the sounds arround me from the double bass, to the trumpet and to the triangle, all musical sounds travel in air with the same speed of sound. That is c = 343 m/s at a temperature of 20°C.
Which property of a wave changes as the wave travels across the boundary between two different media?
it is speed
Does time always move at a constant speed?
The speed of light is always the same as long as it's traveling through the same medium. But its speed is different in different media, and those are all less than its speed in vacuum.
When a wave approaches a boundary between two media obliquely does its direction of motion change or remains the same?
The direction of the wave changes if its speed is different in the two media.
What is the speed of sound of a humming bee?
The speed of sound depends on what the sound is going through, not on what created the sound. If sounds from different sources had different speeds, then there could never be a band, orchestra, or choir.
