Beats

This past Monday my brother and I were playing songs together on the ukulele. Together, we were playing all the classics and the crowd was loving it. As we were playing together we were playing the songs at different frequencies, these different frequencies created beats. Beats are created when two unique frequencies are combined. Unfortunately my brother was not able to accompany me in this picture.

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.
