Question
Define amplitude, time period and frequency with respect to a sound wave. State the relationship between time period and frequency of a wave.
✓

Answer

The maximum displacement of a wave on either side of its mean position is known as its amplitude. Frequency of a wave is the number of oscillations completed by it in one second. Time period of a wave is the time taken by it to complete one oscillation. The time period and frequency of a sound wave are related by the expression
$f = 1/T$
