Draw a diagram to show the wave pattem of high pitch note and a low pitch note, but of the same loudness.
(a) Explain the term 'pitch' of a sound. On what factor does the 'pitch' of a sound depend ?
(b) Draw labelled diagrams to represent sound of (a) low pitch, and (b) high pitch, of the same loudness.
Two musical notes of the same pitch and same loudness are played on two different instruments. Their wave patterns are shown in the figure.
Explain why are the wave patterns different.
