Measure the ratio of the velocity of sound in brass to the velocity of sound in air! A brass rod is rubbed with a bow - which causes the rod to vibrate. Sound waves inside the tube cause lycopodium powder to accumulate at nodal points. By measuring the spacing between the nodal points and comparing this value with the length of the brass rod - the ratio between the speed of sound in brass is obtained. Instructions provided. (36" x 8" x 5"; 3Ibs).
