Dependence of the speed of sound on the properties of the medium:
The speed of sound is variable and depends mainly on the temperature and the properties of the substance through of which the wave is traveling. For example, in low molecular weight gases, such as helium, sound propagates faster compared to heavier gases, such as xenon. In a given ideal gas the sound speed depends only on its temperature. At a constant temperature, the ideal gas pressure has no effect on the speed of sound, because pressure and density (also proportional to pressure) have equal but opposite effects on the speed of sound, and the two contributions cancel out exactly. In non-ideal gases, such as a van der Waals gas, the proportionality is not exact, and there is a slight dependence on the gas pressure, even at a constant temperature. Humidity also has a small, but measurable effect on sound speed (increase of about 0.1% to 0.6%), because some oxygen and nitrogen molecules of the air are replaced by the lighter molecules of water.

What else can I help you with?
Why does the speed of sound change if the temperature of the medium change?
The speed of sound is directly proportional to the temperature of the medium. This is because temperature affects the average speed of the molecules in the medium, which in turn affects how quickly sound waves can travel through it. As temperature increases, the speed of sound also increases due to the higher molecular activity.
A medium can effect speed of sound by changes in what?
When you change density and temperature you effect the way sound travels through a medium.
Does sound velocity change based upon sound frequency?
No, sound velocity does not change based on sound frequency in a uniform medium. In a medium with a constant temperature and pressure, the speed of sound remains constant regardless of the frequency of the sound waves.
What is the effect of temperature on the speed of sound?
Speed of sound depends on the density of the medium. As temperature increases density decreases due to expansion in the volume. Hence speed of sound gets affected by the change in temperature. Speed of sound is directly proportional to the square root of the temperature of the medium.
What makes the speed of sound change?
There are some factors. Temperature, medium are that factors.
Could you run at the speed of sound?
Yes you can change the speed of sound. IF you change the medium the speed changes. IF you change the density of the medium it changes. IF you change the temperature of the medium the speed changes.
Is there any phase change occurred when sound wave refracted from denser medium to a rarer medium?
No, there is no phase change that occurs when a sound wave refracts from a denser medium to a rarer medium. The wavelength and frequency of the wave may change due to the change in speed, but the phase remains the same.
How do sound waves refract when passing through different mediums?
When sound waves pass through different mediums, they can refract, or change direction, due to differences in the speed of sound in each medium. This change in direction occurs because the speed of sound is different in each medium, causing the waves to bend as they travel from one medium to another.
As the temperature of a medium increases the rate of speed of sound through the medium what?
The speed of sound through the medium also increases.
How does sound bending occur when there are changes in the medium through which the sound travels?
Sound bending occurs when there are changes in the medium through which the sound travels because the speed of sound varies depending on the properties of the medium. When sound waves encounter a change in medium, such as going from air to water or passing through different temperatures, they can bend or change direction due to the difference in speed. This bending is known as refraction and can cause sound to be heard differently than expected.
What is the derivation of the speed of sound in a medium?
The speed of sound in a medium is derived from the properties of the medium, such as its density and elasticity. It is calculated using the formula: speed of sound square root of (elasticity / density).
Why is the speed of sound slower then the speed of light?
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.
