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.

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.

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.
