Given information
We have a standing sound wave in a pipe, with an open-end (the air column) and a closed-end (the water surface) as the antinode and node, respectively.
The speed of sound in dry air at 
is 
.
Harmonics are wave mechanics fluctuations that contain a fundamental or information package in a certain frequency range. The receiver gets these data packets and may deduce the emitter's harmonic characteristics. Each musical tone's fundamental vibration is a sinusoidal component of the signal that corresponds to the tone's most basic vibration.
Step-by-step explanation
The device is a tube that is closed. The water level is a node of air displacement since it is the closed end. As the water level drops, the distance between one resonance level and the next corresponds to one-half wavelength between neighboring nodes.
