Notice: The speed of sound changes with temperatureand
a little bit with humidity − but not with air pressure (atmospheric pressure).
The words "sound pressure at sea level" are incorrect and misleading.
The temperature indication, however, is absolutely necessary. The speed of sound in air at 20 degrees Celsius (68 degrees Fahrenheit) is 343 metres per second. That is 1126.547 feet per second.

We can say that it travels faster in denser mediums.
Wiki User
∙ 13y agoIn general, the speed of sound increases or decreases with the density of the material that transports the sound.

Why do different substances travel at different speeds in a chromatography?
yes they do
How do scientist map earths interior?
When earthquakes occur, scientists measure them using seismographs. Earthquakes produce a number of different types of waves. Some run along the surface of the earth. Some travel through the earth. Those that travel through the earth travel at different speeds. It is possible to create similar waves in a lab and measure how those waves travel through different types of materials. Since earthquakes occur all over the world, it is possible to measure the waves from all angles. Thus, if a wave travels a small distance through the core, scientists can tell by differences in speed what it would be if it traveled through all mantle material. So with the difference in speeds in different types of waves, scientists can figure out what is in the earth's interior.
Does sound travel with the same speed through all materials?
no......... the speed changes as it goes through different materials example: when sound goes through air it is faster then when it transfers to go through water because water is more dense and there are more particles for it to have to pass through
What happens when light waves travel through materials?
Light travels through different things (such as air, water, glass, plastic) at different speeds. When a light wave is passing one substance and encounters another (for instance, traveling through air and gets to glass), the difference in the speed causes the light wave to bend. This is what causes rainbows and a spectrum and fish to appear in a different place than where they really are.
Charged particles from the sun that travel through space at high speeds are called?
Solar flares
Does light travel at different speeds through different materials?
no
An ultrasound system can produce images of body structures because sound waves?
travel at different speeds through materials of different densities.
How ultrasound is able to produce images of body structures.?
Because, sound waves travel at different speeds through materials of different densities .
is it true that All light waves travel at different speeds in different materials?
never mind I figured it out. it is true
Why does sound travel at different speeds through different mediums?
because of material density
Can sound travel through different materials?
Sound can travel through a variety of materiels.
When sound and light travel in different materials what changes?
Light travels through a non-mechanical wave, meaning lightwaves don't travel through anything so it never slows or speeds up. The denser the object's molecules are, the faster sounds go through it.
Does sound travel through solid liquid or gas?
It travels through all three, but at different speeds.
Do sounds travel through different materials?
Yes they do.
How do different colors of light travel?
Different Colors Of Light Travel At Different Speeds.
Is it true that different kinds of E-M waves travel through space at different speeds?
No. All E-M waves travel through space at the same speed, known as the"Speed of Light".
Why does speed travel at different speeds in different liquids?
no
