The video tutorial explains how to use a resonance tube to measure the speed of sound. It covers the concept of resonance and standing waves, highlighting how the air column's length affects sound intensity. The tutorial also discusses the effective length of the tube and potential measurement errors. A demonstration with a tuning fork and adjustable water level illustrates how resonance occurs at specific air column lengths. The video concludes with methods to calculate wavelengths and measure sound speed accurately.
