The video tutorial explains how to measure the speed of sound using wooden blocks and a wall. Initially, the method involves clapping blocks and timing the echo, but human reaction time introduces errors. To improve accuracy, the method is refined by clapping multiple times and timing the sequence. The final calculation confirms the speed of sound as 340 meters per second.
