What is the dropple principle in Doppler ultrasonography?
The Doppler principle is simply that sound pitch increases as the source moves toward the listener and decreases as it moves away.
Why does the pitch of sound increase when a listener move towards a stationary source?
Yes, the frequency is higher - same as if the moving source was towards a stationary person -it is all relative
What lets you know that the source of a sound is moving toward or away from you?
When a sound-source moves toward you, its pitch gets higher and the sound gets louder. When it moves away, the pitch lowers and it gets quieter. The frequency change is called the Doppler shift.
Will a listener notice the Dopple effect if they and the source of the sound are traveling towards each other?
The high pitch start would do so later and be higher pitch until the passing of the two moving objects where the low pitch would be lower and end sooner. basically,yes.
What happens when the pitch of a sound seems to changeas the sound source moves toward an observer?
In that situation, what happens is that the pitch of sound seems to change as the sound source moves radially with respect to the observer. When the source approaches the observer, the pitch rises, whereas if the source should recede, then the pitch would fall.
When a listener moves towards a stationary source the pitch of sound increase why?
Yes, the frequency is higher - same as if the moving source was towards a stationary person -it is all relative

How does perceived pitch change as a sound source passes a listener?
The perceived pitch of the sound drops (frequency decreases) as the source transitions from approaching the listener to receding from the listener. The phenomenon is called the "Doppler shift", after the German Physicist who explained it and worked out the math.

What is an apparent change 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.

Why does the pitch of a sound change as the source of the sound that moves past you?
Decreasing velocity, and distance.
How do the Elevator control the Pitch angle?
When pulling on yoke the elevator moves "up" towards the sky, when pressing down on the yoke the elevator moves "down"
What is a apparent change in pitch of a sound caused by the motion of the object making the sound?
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.
