Homework Statement
In a lab that we performed, we had a closed tube with piezo electric transducers on both ends, and they were attached to a frequency generator. We found the frequencies that caused resonance, and the lab wants us to calculate the velocity of the wave using data. The lab says that there are antinode pressure waves at both ends, and therefore, the length of the tube is equal to one wavelength at the lowest frequency.
But at the lowest frequency, wouldn't one antinode to the next correspond to half a wavelength? The two anti nodes in question would be one antinode with max positive displacement to one with the max negative displacement.
