A group of physics students set a tuning fork of 500 Hz just above a big cooking pot. The tuning for is struck and continues to ring throughout the experiment. The students pour water into the pot until they hear the resonance of the fundamental mode.

1. If the cooking pot is 0.2 meters tall, how long is the wavelength of the resonance created? 0.8

2. What is an estimate for the speed of sound in this situation? 400m/s

Question want explanation and answer to:

3. You may discover that the speed of sound seems a bit off. Write down some ideas on why that is.
