Measuring the Speed of Sound in Air Using a Smartphone and a Cardboard Tube

This paper demonstrates a variation on the classic Kundt's tube experiment for measuring the speed of sound. The speed of sound in air is measured using a smartphone and a cardboard tube, making the experiment very economical in terms of equipment. The speed of sound in air is measured to within 3\% of the theoretical prediction.
