What else can I help you with?
A train passes by blowing its whistle As it passes the sound of the whistle is lower than it was on its way towards you This is due to?
a change in the sound's frequency caused by the motion of the sound's source
What happens if the source of a sound is toward you at a high rate of speed?
If the source of a sound is moving towards you, then the pitch of the soundyou hear is higher than the pitch of sound that the source is actually emitting.The rate of speed doesn't matter.BTW ... this also happens if you are moving toward the source.
What happens to sound waves as they move away from the source of the sound?
They get distant and more quieter
What happens when the pitch of a sound seems to changeas the sound source moves toward an observer?
In that situation, what happens is that the pitch of sound seems to change as the sound source moves radially with respect to the observer. When the source approaches the observer, the pitch rises, whereas if the source should recede, then the pitch would fall.
What happens to the speed of sound when it passes through a solid?
It is reflected because of the way the particles are transmited
How does perceived pitch change as a sound passes a listener?
The perceived pitch of a sound can change as it passes a listener due to the Doppler effect. If the sound source is moving toward the listener, the pitch will be higher; if the source is moving away, the pitch will be lower. This is because of the compression or expansion of sound waves as the source moves relative to the listener.
When a sound source moves towards you what happens to the wave?
It stays the same.
What happens to the speed of a sound wave as it passes from the air into the ground?
The speed of a sound wave increases when it passes from air into the ground. This is because sound waves travel faster in solids than in gases, due to the higher density and rigidity of the solid material.
What happens to the pitch as a sound source moves closer to listener?
As a sound source moves closer to a listener, the pitch of the sound will increase. This effect is known as the Doppler effect, where the perceived frequency of a sound wave increases as the source moves towards the listener.
When the source of a sound is moving the sound waves spread out as it travels away from the listener As this happens what does the listener observe?
a lower-pitched sound
What happens to sound waves when the source of a sound is moving toward you?
When the source of a sound is moving toward you, the sound waves emitted by the source are compressed, resulting in a higher frequency of the sound you hear. This phenomenon is known as the Doppler effect and is commonly experienced with sirens from emergency vehicles approaching you.
What happens to the speed wavelength and frequency when sound wave passes from cool air into warmer air?
When a sound wave passes from cool air to warmer air, its speed increases due to the higher temperature in the warmer air, resulting in a shorter wavelength. This increase in speed causes the frequency of the sound wave to remain constant, as frequency is determined by the source of the sound rather than the medium it travels through.
