What does high pressure do to sound?
The speed of sound does not change with atmospheric pressure. The speed of sound changes with temperature.
The peak of sound wave where the lowest air pressure occurs?
The speed of sound does not change with atmospheric pressure. The speed of sound changes with temperature.
Is sound produced when there are increases in pressure or oscillations in pressure?
The speed of sound does not change with atmospheric pressure. The speed of sound changes with temperature.
What would be an observable change in sound when the frequency changes?
what would be an observable change in sound when the frequency changes
What is the effect of temperature on velocity of sound?
Formula for speed of sound c = 331 + 0.6 × ϑ ϑ = temperature in degrees celsius. At ϑ = 20°C we get a speed of sound c = 331 + 0.6 × 20 = 343 m/s. 1 °C change of temperature is equal to 60 cm/s change of speed of sound. The speed of sound changes clearly with temperature, a little bit with humidity − but not with air pressure (atmospheric pressure). The words "sound pressure at sea level" are incorrect and misleading in the case of "speed of sound". The temperature indication, however, is absolutely necessary. The changing of atmospheric pressure does not change the sound of musical instruments in a concert hall or in a room. Look at link: "Temperature Dependence of Physical Entities".
What is a property of sound that changes with frequency?
If you change sound's frequency and hold the velocity constant, the sound's wavelength also changes. If you change sound's frequency and keep the wavelength constant, then velocity also changes.
What does high pressure do to sound?
The speed of sound does not change with atmospheric pressure. The speed of sound changes with temperature.
What property of sound is affected by change in air temperature?
The speed, and therefore also the wavelength (for sound of a given frequency), are affected by temperature.
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.
The peak of sound wave where the lowest air pressure occurs?
The speed of sound does not change with atmospheric pressure. The speed of sound changes with temperature.
Is sound produced when there are increases in pressure or oscillations in pressure?
The speed of sound does not change with atmospheric pressure. The speed of sound changes with temperature.
How much does the velocity of sound changes for every 1 degree change in temperature?
0.61 meters a second
Why does the speed of sound change if the temperature of the medium change?
because the density of the medium changes with temprature

Explain why the speed of sound changes if the temperature of the medium changes?
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.
