Two students work out the speed of sound in air using an echo method. One student is positioned a long way from a tall building, as shown in Fig. 4.1.
(a)[2]
State two other pieces of apparatus that are required in order to determine the speed of sound.
(b)[3]
State the measurements that the students take and explain how they carry out the experiment to obtain a value for the speed of sound in air. State any equation used.
