What happens to the pitch when the sound source moves away from you?
The pitch lowers as the wavelength of the sound increases. It's called the Doppler effect
Why does the Doppler effect explain why a siren's pitch decreases as it moves away from you?
The siren moves away from the sound waves it has already produced, increasing their wavelength. Make sure it says INCREASING and not DECREASING -Apex :)
When a listener moves toward or away from a source of sound does the wave speed or wave frequency change?
When a source moves toward the Earth its wavelength is shortened, a phenomenon known as blueshift. When a source moves away from the Earth its wavelength is increased, a phenomenon known as redshift.
Does a deeper sound have a greater wavelength?
A sound that is lower in pitch has a larger wavelength. Some animals such as Elephants and Whales use that sound to communicate with each other. The larger wavelength lets them communicate with animals miles away.
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.
Why does the frequency of sound waves change for a listener when the sound source moves towards or away from the listener?

What is an increase in the wavelength of light as a galaxy moves away from earth?
Red Shift

Which color has the longest wavelength and shows that a star is moving away from us?
It's not that a particular color has the longest wavelength. The wavelength BECOMES longer when a star moves away from us. Red light has a longer wavelength than blue, for example.

What occurs when a sound moves away from you?
the sound´s frequency decreases
When a sound source moves towards you what happens to the wave speed?
It is called the Doppler Effect. When the source of waves approaches you (can be any type of waves - mechanical, electromagnetic like light etc.), the wavelength gets smaller and frequency higher. So when a car approaches you, you hear higher tone than when it departs.
Which refers to the change in wavelength tht occurs when an object moves toward or away from a source?
doppler effect
