Sound Waves in Physics
In this a physics lab this week, students explored聽the properties of sound, particularly聽how the frequency of sound affects the way we hear it. They first used a microphone to record the sounds of two different tuning forks and measured the frequencies of the sound from their data. Students聽found that a higher frequency makes a higher pitched sound. Then they explored the different sound waves produced by saying the vowel 鈥淓鈥� and the vowel 鈥淥鈥�. They found that an 鈥淓鈥� has a different set of frequencies than the 鈥淥鈥�, and well as a different wave shape! The lab served as a great visual of the principles students have been learning in physics recently.
