(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.
By reducing the amplitude of a sound wave, its:
(a) pitch increases (b) loudness decreases
(c) loudness increases (d) pitch decreases.
Which of the following characteristics of sound wave is considered to differentiate two sound wave of same pitch and loudness?
