The frequency, as observed by the receiving end, will be less than the frequency at which the wave was emitted.

What is the frequency in a sound wave created by a moving object?
It a bouncing sound
What is an sound vibration?
Sound is produced when an object moves or vibrates. Without movement there could be no sound. When an object moves or vibrates, the air molecules around the object also vibrate. Vibrating objects (as long as they are not in a vacuum) produce sound.
When were Doppler ultrasounds invented?
Christian Doppler discovered the Doppler effect in 1842. He observed that the frequency of sound changes as the object of the sounds moves and the detector of the sound moves. Radar and medical devices use the Doppler effect to locate and provide images of scanned objects.
A low frequency sound is produced by a sound wave that?
An object vibrating relatively slowly produces sound waves that have low frequency and long wavelength.
How do vibrations affect sound?
a vibrating body produces sound. ie only if an object vibrates will it produce sound. the faster the object vibrates, the louder the sound and vice-versa. the no of vibrations per seceon is called frequency. thus if an object has a higher frequency, then it produces a louder and shriller sound...
What occurs when a sound moves away from you?
the sound´s frequency decreases

Why does the frequency of sound waves change for a listener when the sound source moves towards 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.
When the frequency of sound waves matches the natural frequency of an object the result can be?
the result is resonance

The natural frequency of an object depends on its?
It depends on two variables v : speed of sound within this object L : main lenght of this object The natural frequency of the object will be v/L
What happen to the speed of sound as it moves from water to air?
It will slow - sound moves faster in water than in air.
What is an apparent 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.
When a sound wave causes an object to vibrate at its natural frequency it is?
vibrate at its natural frequency. WHS AOEC
