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? I think it is 0.8

Question want explanation and answer to:

2. What is an estimate for the speed of sound in this situation?
