The velocity of sound in air is independent of change in what variable?
The velocity of sound in air is independent of changes in frequency. Sound waves travel at a constant speed determined by the properties of the medium they are traveling through, such as air temperature and pressure.
Why are sound waves known as pressure waves?
Because it is pressure that actually propagates through the medium. When air is the medium, air molecules are displaced outward and then back, in unison with the sound generating object. This 'wave' of pressure, much like a ripple on water, moves through the air outward from the source.
When a gong vibrates the air particles next to athe gong do not reach your ears yet you hear the sound of the gong explain?
Sound propagates as a disturbance in air pressure. The movement of the gong first pushes air particles out of the way, creating a region of high pressure, but then moves back in the other direction, creating a region of low pressure, which the air particles move back to fill. So, air particles do move locally as the pressure changes, but there is no net transport of air. The energy in the wave is carried forward as a moving change in pressure. This change in pressure is detected by your ears. One can make a loose analogy with surface waves on water. Drop a pebble into a still pond. Waves will propagate outward from the point of contact, where water was initially displaced. The water waves propagate outward as the height of the water changes at each point, yet there is no net flow of water.
Why does sound travel faster at the bottom of a mountain than it does at the top?
Speed of sound in air is dependent on the air pressure, and air pressure is dependent on height above sea level. Up high, pressure is lower and speed of sound is different.
What does not affect the speed of sound in air?
I think you're looking for a change in medium - that is to say, the frequency of a sound wave does not change as it passes from one material to another (like when sound travels from air to water), although it does affect speed, changing the wavelength.
How does air pressure change the effect of sound waves compression and rarefaction?
Air pressure does not affect transverse sound waves. The temperature is most important to do that. The speed of sound in air is determined by the air itself and is not dependent upon the amplitude, frequency, or wavlength of the sound. Look at the link: "Speed of Sound in Air and the effective Temperature".
Does sound reaches our ears due to change in air pressure?
Yes, sound reaches our ears due to vibrations in the air, which cause changes in air pressure. These pressure changes are detected by the ear and converted into signals that our brain interprets as sound.
The peak of sound wave where the lowest air pressure occurs?
The peak of a sound wave where the lowest air pressure occurs is called the rarefaction. This is the point where the air molecules are spread out, creating a region of decreased pressure compared to the surrounding air.
The velocity of sound in air is independent of change in what variable?
The velocity of sound in air is independent of changes in frequency. Sound waves travel at a constant speed determined by the properties of the medium they are traveling through, such as air temperature and pressure.
Is sound a pressure wave?
Yes. Sound is made by moving air. Condensing and rarefying the air. A speaker moves back and forth to move air and make sound.
What make cloud types change?
air pressure
Is sound produced when there are increases in pressure or oscillations in pressure?
Yes, sound is produced when there are changes in pressure that cause the particles in a medium to oscillate. The pressure variations create sound waves that travel through the medium, such as air or water, and are detected by our ears as sound.
What does it take to make a sound?
Sound is created by vibrations in the air. When an object vibrates, it creates pressure waves that travel through the air to our ears. These pressure waves are then interpreted by our brains as sound.
How does air pressure effects a sound wave?
Air pressure can affect a sound wave by changing the speed at which the wave travels. Higher air pressure leads to faster sound wave propagation due to increased molecular collisions, while lower air pressure can slow down sound waves. This can alter the pitch or tone of the sound.
Does anything that vibrates make a sound?
No, not necessarily. In order for something that vibrates to make a sound, the vibrations need to create pressure waves in a medium, such as air, that can be detected by our ears. If the vibrations do not create these pressure waves, then no sound will be produced.
Does air at high pressure transmit sound faster than air at low pressure?
No. The speed of sound in air changes clearly with temperature, a little bit with humidity − but not with air pressure (atmospheric pressure).
How does the frequency of a sound wave depend on the pressure of the air?
The speed of sound is not greatly affected by pressure in an ideal gas. Air is not an ideal gas, so there may be some small effect, but temperature and humidity will be much more influential. ================================ Answer #1: The frequency of sound is completely determined by the source of the sound. Once the sound leaves the source, the frequency doesn't change.
