Well i guess the noise starts getting louder and louder as the train is coming?

What happens if two sound waves having the same frequency interfere in phase?
they come closer
What happens to a frequency heard when an observer begins toward the stationary source of a sound?
.The frequency increases
If the frequency of a sound wave is multiplied by ten what happens to the wave length?
it gets divided by 10; frequency = speed/wavelength; wavelength = speed/frequency
What happens to the frequency and Amplitude when you scream?
amplitude increases (louder the sound is, bigger is the amplitude)
What happens to a sound source as it approaches?
It appears to have a higher frequency due to the Doppler Effect.
What happens if two sound waves having the same frequency interfere in phase?

What happen as the frequency of a sound wave increase?
The frequency of a sound wave increases because either the object making the sound is getting closer to you, or you are getting closer to it. Frequency tells you how many complete sound waves are produced in a certain amount of time (usually a second). As you get closer, the sound waves don't have to travel so far to reach you, so you hear them more often or more frequently; i.e., from your perspective, the frequency increases. Our brains interpret higher frequencies as higher pitched sounds.When the frequency of a sound wave increases, so does it's pitch In other words, you would hear a higher tone.
What happens to a frequency heard when an observer begins toward the stationary source of a sound?
.The frequency increases
What happens when a sound source passes by you?
it's frequency increases
After an approaching ambulance passes a stationary observer what does the frequency of the sound of the siren heard by the observer appear to do?
Soften... It is lower due to the Doppler effect. Decrease =]
What happens to a sound when its rate of vibration decreases?
It becomes a lower frequency.
How is pitch determined?
the closer together the sound is the higher it is and vise verser
What happens to the pitch of a note when the frequency is increased?
If the frequency of a sound is increased, the pitch goes higher.
If the frequency of a sound wave is multiplied by ten what happens to the wave length?
it gets divided by 10; frequency = speed/wavelength; wavelength = speed/frequency
What happens to a sound source as it approaches?
It appears to have a higher frequency due to the Doppler Effect.
What happens to the frequency and Amplitude when you scream?
amplitude increases (louder the sound is, bigger is the amplitude)
What happens to the sound waves created as a person sings higher and higher notes?
The frequency of the sound wave increases in this case.
