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 else can I help you with?
A high-pitched sound has a greater?
A high-pitched sound has a greater frequency, meaning it oscillates more rapidly than a low-pitched sound. This frequency is perceived by our ears as a higher pitch.
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.
Whenever a source of sound moves the frequency heard by the observer is Less than that of the source?
To be more specific, a sound source moving toward you will appear to emit a sound of higher frequency than actual. Conversely, a sound source moving away from you will appear to emit a sound of lower frequency than actual. See "the Doppler effect."
What is a change in frequency and pitch as a source of sound moves toward or away from you?
The change in frequency and pitch of a sound as it moves toward or away from you is known as the Doppler effect. When a sound source approaches, the frequency and pitch appear higher than they actually are. Conversely, when the source moves away, the frequency and pitch appear lower.
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.
A cumulative frequency distribution would provide?
The cumulative frequency or the probability of an observed value being less than or equal to a given value. By extension, it would also give the probability of a greater value being observed.
What would be evidence of a galaxy moving towards earth?
A blueshift in the galaxy's spectrum - that is, the frequency of the light, as observed by us, is greater than when it was emitted.
What would evidence of a galaxy moving toward Earth?
A blueshift in the galaxy's spectrum - that is, the frequency of the light, as observed by us, is greater than when it was emitted.
Is frequency a greater than normal occurrence of the urge to urinate?
No. Frequency is just a measure of "how often". It can be less than, equal to or greater than normal.
Do sound waves have a greater frequency than gamma rays?
No. The frequency of gamma rays is several orders of magnitude greater than that of any sound wave.
Why uplink frequency is greater than downlink frequency can you provide me these details with technical data?

If the frequency of light is greater than the threshold frequency will photoelectric effect starts?
Yes - that's how it works.
What is the wavelength and frequency for radio waves?
The wavelength is greater than 300E6/300E9 = 1 mm and the frequency is less than about 300 Gigacycles.
A high-pitched sound has a greater?
A high-pitched sound has a greater frequency, meaning it oscillates more rapidly than a low-pitched sound. This frequency is perceived by our ears as a higher pitch.
What name is given to the frequency that is greater than which humans can hear?
ultrasonic
Is a teakettle whistle have greater frequency than a drum beat?
false because it does
How do you find less than cummulative and greater than cummulative frequencies?
To find less than cumulative frequency, you sum the frequencies of all classes up to and including the current class. Conversely, for greater than cumulative frequency, you start from the total frequency and subtract the cumulative frequency of the current class and all preceding classes. This way, you can determine how many observations fall below or above a specific value in a frequency distribution.
