Sound is a moving along as a wave in the air. The pitch you hear depends on how
many waves per second impinge on your ear. When you move towards the source,
more waves pass you each second ---> higher pitch.
Why do more waves pass you each second when you move toward the source ?
Try this: Think of standing at the bottom of an escalator, with the steps coming
down toward you. Now, if you start walking up the staircase next to the escalator,
the escalator steps will pass you faster ---> more of them each second.

What frequency will be detected by a stationary listner if sournce of sound is moving towards him?
The frequency detected by a stationary listener will be higher than the frequency emitted by the source. This is due to the Doppler effect, where sound waves are compressed as the source moves towards the listener, causing a perceived increase in frequency.
When you are moving toward a stationary source of a sound its frequency will appear lower than it actually?
As you move toward a stationary source of sound, the frequency of the sound waves will appear higher than they actually are due to the Doppler effect. This effect is caused by the compression of sound waves as you move closer to the source, which increases the perceived frequency.
Is it true or false for a stationary observer when the source of a sound is moving its pitch appears to change?
True. When the source of a sound is moving relative to a stationary observer, the pitch of the sound appears to change due to the Doppler effect. If the source is moving towards the observer, the pitch is heard higher, and if the source is moving away, the pitch is heard lower.
What is the difference between a mobile source and a stationary source?
A mobile source refers to a source of pollution that moves or is not fixed in one location, such as cars or trucks, while a stationary source refers to a source that remains in one place, like a factory or power plant. Mobile sources contribute to pollution through emissions while stationary sources produce pollution by releasing harmful substances into the air or water.
What is the apparent change in frequency of a sound as the source moves in relation to the listner?
The apparent change in frequency of a sound as the source moves in relation to the listener is known as the Doppler effect. If the source is moving towards the listener, the frequency heard is higher (shifted towards higher frequencies), and if the source is moving away from the listener, the frequency heard is lower (shifted towards lower frequencies).
What frequency will be detected by a stationary listner if sournce of sound is moving towards him?
The frequency detected by a stationary listener will be higher than the frequency emitted by the source. This is due to the Doppler effect, where sound waves are compressed as the source moves towards the listener, causing a perceived increase in frequency.

True. When the source of a sound is moving relative to a stationary observer, the pitch of the sound appears to change due to the Doppler effect. If the source is moving towards the observer, the pitch is heard higher, and if the source is moving away, the pitch is heard lower.
When a stationary observer when the source of a sound is moving its pitch appears to change?
true
When a listener moves towards a stationary source the pitch of sound increase why?
Yes, the frequency is higher - same as if the moving source was towards a stationary person -it is all relative
When the source of a sound is moving its speed increases.?
B. False

For a stationary observer when the source of a sound is moving it's pitch appears to change?
Yes, that's correct. When a sound source is moving toward an observer, the pitch appears higher (frequency increases) due to compression of sound waves, and when moving away, the pitch appears lower (frequency decreases) due to stretching of sound waves. This effect is known as the Doppler effect.
What frequency will be detected by a stationary listener if source of sound is moving towards him?
The frequency detected by a stationary listener will be higher than the actual frequency emitted by the moving source. This effect is known as the Doppler effect, and it occurs because the sound waves are compressed as the source moves towards the listener, resulting in a perceived increase in frequency.
For a stationary observer when the source of a sound is moving its?
When the source of a sound is moving towards a stationary observer, the pitch of the sound will appear higher (increased frequency). When the source is moving away from the observer, the pitch will appear lower (decreased frequency). This phenomenon is known as the Doppler effect.
When you are moving towards a stationary source of a sound its frequency will appear lower than it actually is?
Yes, when you are moving towards a stationary source of sound, the frequency of the sound waves will appear higher than they actually are. This phenomenon is known as the Doppler effect, where the motion of the observer causes a shift in perceived frequency.
