The apparent change in the frequency of a sound emitted by a moving object as it passes a stationary observer is called the what effect?
Doppler effect.
What is the apparent change in frequency of a sound emitted by a moving object as it passes a stationarybobserver called?
The apparent change in frequency of a sound emitted by a moving object as it passes a stationary observer is called the Doppler effect. This effect causes the perceived frequency of the sound to change depending on the relative motion of the source and the observer – it is higher as the source approaches the observer and lower as it moves away.
How does frequency of the ultrasonic waves of the echo from the stationary object compare with frequency of the ultrasonic waves of the probe?
The frequency of the ultrasonic waves of the echo from a stationary object is the same as the frequency of the ultrasonic waves emitted by the probe. The echo frequency remains constant as it reflects off the stationary object back to the probe.
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.
The apparent change in the frequency of a sound emitted by a moving object?
The apparent change in the frequency of a sound emitted by a moving object is known as the Doppler effect. When the object is moving towards an observer, the frequency is perceived as higher (pitched up), and when the object is moving away, the frequency is perceived as lower (pitched down). This effect is commonly experienced with passing vehicles or sirens.

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.
After an approaching ambulance passes a stationary observer what does the frequency of the sound of the siren heard by the observer appear to do?
The frequency of the sound of the siren appears to decrease as the ambulance moves away from the observer. This is due to the Doppler effect, which causes a shift in frequency as the source of the sound moves relative to the observer.
The apparent change in frequency as a wave source moves in relation to the listener is called?
The Doppler effect is that apparent change of the frequency of a moving object when someone is stationary. A car may seem to get louder as it gets closer to a person and then the sound will drop as the car gets away.
How does the frequency of re-emitted light in a transparent material compare with the frequency of the light that stimulates its re-emission?
The frequency of re-emitted light in a transparent material is the same as the frequency of the light that stimulates its re-emission. This is due to the conservation of energy principle, where the energy of the absorbed photon is re-emitted as a photon of the same frequency.
Doppler effect with two people moving to each other?
In this case, the frequency of a wave emitted by one person would increase (be perceived as having a higher frequency) by the other.In this case, the frequency of a wave emitted by one person would increase (be perceived as having a higher frequency) by the other.In this case, the frequency of a wave emitted by one person would increase (be perceived as having a higher frequency) by the other.In this case, the frequency of a wave emitted by one person would increase (be perceived as having a higher frequency) by the other.
What is the solution to the Doppler effect problem involving a moving source of sound and a stationary observer?
The solution to the Doppler effect problem involving a moving source of sound and a stationary observer is to use the formula: f' f (v vo) / (v vs), where f' is the observed frequency, f is the emitted frequency, v is the speed of sound, vo is the speed of the observer, and vs is the speed of the source. This formula helps calculate the change in frequency perceived by the observer due to the motion of the source.
How do you calculate the frequency of light emitted in chemicals?
There are several ways to calculate the frequency of light emitted or absorbed by different chemicals, and they depend on what you already know. For example, if you know the energy of the particle, then you can calculate frequency from E = planck's constant x frequency and solve for frequency. If you happen to know the wavelength, then you can use C = wavelength x frequency and solve for frequency (where C = speed of light).
