Sound Waves

As I was doing my normal singing practice that I do every Sunday I noticed some properties that we are currently learning in physics. As I began to sing higher and lower notes I realized that the frequency of the soundwaves were changing. This means that a note of higher frequency had a smaller wavelength then a note of lower frequency. I also realized that as I sang louder and softer this did not affect the frequency of the note I was singing. I love to sing.
