Using cylinders 3 cm in diameter and 0.50 m long, students constructed a musical instrument by placing liquid in the cylinders. The temperature was about -10 degrees celcius and they can use the formula for the speed of sound in air: (331.3 + 0.606/oC*T) Where T is in celcius and the velocity is is m/s. In order to create a pitch (frequency) of 256 Hz, 512 Hz, and 1024 Hz, to what dephts did the students fill three of the containers?
