Sound Waves: Sub Woofers

Everyday when I drive, I listen to music. I did not realize that what was happening when I was playing the music, sound waves were being produced. I thought of this because of what we are learning in class. The sub woofers in my truck are good examples of sound waves. They make a lot of vibrations to creat the loud booming sound. If we were to take the sound of the subs and use that sound in our first lab, the waves would have long wave lengths and huge amplitudes. Subs are longitudinal waves because the sound generated from the subs are pushed outwards. It is not like a flag where the motion has to go up and down to create the wave.
