My picture above is a speaker. Speakers produce sound waves so that we can hear the sound. Now that we have learned more about waves, I now understand how changing the music up and down makes the volume change with physics. When we turn the music up, we are actually increasing the frequency and the wave length. This results in a faster velocity of waves and therefore the sound is louder because the waves are traveling faster. When the sound is turned down, the frequency and wave length is decreased and the velocity is also decreased. The sound is harder to hear because the wave length is being reduced. Physics has helped me understand why things happen in life like the sound speaker.
oh sick blogpost jantzen! it really helped me understand this last lesson thanks for all of the help mentor.
ReplyDeleteGreat blogpost Jantzen it helped me understand more about unit 9 for the test.
