Why does the sound of something moving away from you seem to change to a lower and lower pitch? A) As the source moves away, the increased distance creates more interference; so the pitch drops. B) As the source moves away, the frequency of the sound waves is being compressed, so the pitch drops. C) As the source moves away, the sound waves speed up to reach the observer; this causes the pitch to drop. D) As the source moves away, the sound waves stretches out relative to the person standing still; so the pitch drops.

I have another question...
shamim
  • shamim
U know low pitch means low frequency of sound wave. Right?
anonymous
  • anonymous
Yes I do.
shamim
  • shamim
Pitch is proportional to the frequency
anonymous
  • anonymous
It is the Doppler effect right?

Source of a sound wave is going away frm me. So frequecy listening by me will b lower than the original frequency
shamim
  • shamim
Yes it is dopler sffect

Oops sorry wrong one!lol! A piece of driftwood moves up and down as water waves pass beneath it. However, it does not move toward the shore with the waves. What does this demonstrate about the propagation of waves through a medium? A) Waves transmit energy but not matter as they progress through a medium. B) Waves transmit matter but not energy as they progress through a medium. C) Waves do not transmit matter or energy as they progress through a medium. D) Waves transmit energy as well as matter as they progress through a medium.
