This diagram shows a loudspeaker producing a sound and a microphone connected to a cathode-ray oscilloscope (CRO).

Question:

a. Sound is described as a longitudinal wave. Describe sound waves in terms of the movements of the air particles.

b. The time-base on the oscilloscope is set at 5 ms div⁻¹. Calculate the frequency of the CRO trace.

c. The wavelength of the sound is found to be 1.98 m.

Calculate the speed of sound.
