Sound was the main topic of discussion in class this week. Although I wasn't here for the first half of the lab, the second half of the lab consisted of measuring the length of a palm pipe, measuring the diameter of the pipe, and finally solving the wavelength of the palm pipe. The palm pipe I got was .058m, so the wavelength was .247m. After plugging my numbers into the equation velocity=frequency times wavelength, I was able to solve the frequency, which was 1388.66hz.

To end the lab, the whole class played their palm pipes to the tune of "Twinkle Twinkle Little Star" with their respective notes.
