What is the perception in the change of a sound frequency as the source moves closer or farther from The listener?
As the source of a sound moves closer to a listener, the frequency of the sound will appear to increase, resulting in a higher pitch. Conversely, as the source moves farther away, the frequency will appear to decrease, resulting in a lower pitch. This phenomenon is known as the Doppler effect.

When both source and listener move in the same direction with a velocity equal to half the velocity of sound the change in frequency of the sound as detected by the listener is?
The frequency heard by the listener will increase as both the source and listener move towards each other. The change in frequency is given by the Doppler effect equation: f' = f * (v + v_L) / (v - v_S) where f' is the observed frequency, f is the actual frequency, v is the speed of sound, v_L is the speed of the listener, and v_S is the speed of the source.
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 is the apparent change in the freqency of a sound caused by the motion of either the listener o the source of sound?
The apparent change in frequency of a sound caused by the motion of either the listener or the source of sound is known as the Doppler effect. If the source is moving towards the listener, the frequency appears higher (higher pitch), and if the source is moving away, the frequency appears lower (lower pitch).
Sound change in frequency due to motion?
The Doppler effect is the change in frequency of sound waves as a sound source or listener moves relative to each other. When a source is moving towards a listener, the frequency appears higher (shorter wavelength) due to compression of waves. When moving away, the frequency seems lower (longer wavelength) due to stretching of waves.
When a listener moves toward or away from a source of sound does the wave speed or wave frequency change?
When a source moves toward the Earth its wavelength is shortened, a phenomenon known as blueshift. When a source moves away from the Earth its wavelength is increased, a phenomenon known as redshift.
When both source and listener move in the same direction with a velocity equal to half the velocity of sound the change in frequency of the sound as detected by the listener is?
The frequency heard by the listener will increase as both the source and listener move towards each other.

How does Doppler effect on frequency and pitch?
The Doppler effect on frequency and pitch is the change in perceived frequency and pitch of a sound as the source moves relative to the listener. When the source is moving towards the listener, the perceived frequency and pitch increase, and when the source is moving away, they decrease. This effect is commonly experienced with moving vehicles and emergency sirens.
How does perceived pitch change as a sound source passes a listener?
The perceived pitch of the sound drops (frequency decreases) as the source transitions from approaching the listener to receding from the listener. The phenomenon is called the "Doppler shift", after the German Physicist who explained it and worked out the math.
What happens to the frequency of each wave as it gets farther away from the source?
Nothing. If the frequency of a wave depended on its distance from the source, then . . . -- The key of the marching band would change as it passed you in the parade. -- So would the colors on the flag.
What is an apparent change in frequency of a sound source that moves relative to an observer?
The Doppler Effect. It's a change in frequency cause by the motion of the sound source, the motion of the listener, or both. As a source of sound approaches, observers hear a higher frequency. When the sound source moves away, observers hear a lower frequency. This effect was discovered by an Austrian scientist named Christian Doppler. Example: An ambulance siren. As the ambulance approaches a stationary observer, the frequency seems to increase. As the ambulance moves farther away, the loudness of the siren seems to decrease.
Why does the frequency of sound waves change for a listener when the sound source move toward or away from the listener?
This is an example of the Doppler effect. Sound is composed of waves. A particular vibration produces a sound wave with a particular wavelength. When the sound source moves towards a listener the waves are "bunched up". That results in a shorter observed wavelength and thus a higher frequency. When the sound source moves away the opposite happens. The frequency of the sound waves decreases.

What Doppler effect is the the change in sound caused by the motion of the sound source motion of the listener or both?
Both. The Doppler effect occurs when there is relative motion between the sound source and the listener. If either the source or the listener is in motion, it will cause a shift in the frequency of the sound waves that are perceived.
