When does the Doppler effect happen?
The doppler effect happens when the source of a sound is moving. When it is moving towards you, it sounds louder and can have a different pitch and when the source is moving away, its a quieter more "far-off" sound. This is because when the source is moving, the sound waves are getting compressed in front of it due to relative velocity. Once the sound wave is made, it's speed is independent of its source. This is also how a sonic boom happens. At super sonic speeds, the sound barrier is broken which is the build up of all the sound waves created.
What is the Doppler effect on sound?
The Doppler effect is a phenomenon observed whenever the source of waves is moving with respect to an observer. The Doppler effect can be described as the effect produced by a moving source of waves in which there is an apparent upward shift in frequency for the observer and the source are approaching and an apparent downward shift in frequency when the observer and the source is receding. The Doppler effect can be observed to occur with all types of waves - most notably water waves, sound waves, and light waves.
What phenomenon is the basis of police radar and makes light or sound waves increase in frequency if the source is moving toward the observer and decrease if the source is moving away?
Its called the doppler effect.
What happens if a source of sound is moving toward you at a high rate of speed?
The waves compress which causes a lower tonal quality.
How are sound waves unique?
Sound waves move away from the source of energy, but other sorts of waves move perpendicular (at a right angle) to the energy source

When the source of a sound is moving the sound waves spread out as it travels away from the listener As this happens what does the listener observe?
a lower-pitched sound

What are the differences of sound and water waves in terms of source?
Sound and water waves differ in one main way in terms of source, although they are very alike. Sound waves are generated by a verifiable sound source, such as vibration.
Why does moving away from a radio affect the loudness you hear?
because sound waves spread out, intensity decreases with distance from the source.
What happens if a source of sound is moving toward you at a high rate of speed?
The waves compress which causes a lower tonal quality.
Why is a bow wave produced when a wave source moves?
Like the Doppler effect, the source of the waves is moving, this time in the same direction as the wave front and therefore catching up to the waves that were produced earlier, resulting in a bunching up effect of waves in front of the source and a spreading out of wave fronts behind the source. Does this look like a bow to you>
What is the energy source for sound waves?
That varies, depending on what causes the sound waves.
When a sound source approaches the pitch you hear is higher than when the source is not moving?
Yes. This is called a blue shift, and is caused by shortening of the period of waves. It's inverse is a red shift, which occurs when the observer is moving further away from the source of sound. These are both examples of Doppler Shifts.
What is the source of energy for a sound wave?
The source of energy for sound waves are vibrations.
