How the motion and frequency of a wave source affects the waves that source produces?
The motion of a wave source affects the wavelength and amplitude of the waves it produces. A moving source can either compress or expand the waves it emits, leading to a change in frequency, called the Doppler effect. A higher frequency is produced by a faster-moving source, resulting in a higher pitch in sound waves or a shift towards the blue end of the spectrum in light waves.
What else can I help you with?
What is The motion of the pulse with the respect to the source?
The motion of a pulse is affected by the motion of the source. If the source is moving towards the observer, the pulse will be compressed and its frequency will increase. If the source is moving away from the observer, the pulse will be stretched out and its frequency will decrease.
A source that is vibrating with simple harmonic motion produces a?
A source vibrating with simple harmonic motion produces a sinusoidal wave.
Why does observer measure waves from an approaching source as having a higher frequency than if the source were standing?
This is due to the Doppler effect, where the motion of the source compresses the waves as it approaches the observer. This compression increases the frequency perceived by the observer. If the source were stationary, there would be no relative motion and no frequency shift.
Why the observed frequency is greater than the frequency of the source?
The observed frequency can be greater than the frequency of the source due to the Doppler effect, where the relative motion between the source and observer causes a shift in the frequency of the wave. When the source is moving towards the observer, the observed frequency is higher, and when the source is moving away, the observed frequency is lower.
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).
The change in the Doppler effect causes what not to occur with it?
The change in the Doppler effect does not cause a change in the frequency of the wave source itself; it only affects how the frequency of the wave is perceived by an observer in relative motion to the source.
What is The motion of the pulse with the respect to the source?
The motion of a pulse is affected by the motion of the source. If the source is moving towards the observer, the pulse will be compressed and its frequency will increase. If the source is moving away from the observer, the pulse will be stretched out and its frequency will decrease.

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.
What is the relationship between the frequency of the wave source and the wave length of the waves?
The product of (frequency) times (wavelength) is always the same number,as long as the waves stay in the same substance. That number is the speedof the waves through the substance.
What happens to a frequency heard when an observer begins toward the stationary source of a sound?
.The frequency increases
What is a phenomenon that depends on the relative motion of the source and the observer?
The Doppler effect is a phenomenon that depends on the relative motion of the source and the observer. It is the change in frequency or wavelength of a wave in relation to an observer moving relative to the source of the wave.
For an observer who stays in one spot when the source of a sound is moving the sound wave's?
frequency and pitch would change as the source moves. As the source moves away, the frequency and pitch decrease, and as the source moves closer, they increase. This is due to the Doppler effect, where the relative motion between the source and observer causes a shift in frequency.
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.
