Question
Define amplitude, time period and frequency with respect to a sound wave. State the relationship between the time period and the frequency of a wave.
✓
Answer
Amplitude is the maximum displacement of a wave on either side of its mean position. Time period of a wave is the time taken by it to complete one full oscillation. It is denoted by $T$ and is measured in seconds. Frequency of a sound wave is the number of oscillations completed by it in one second. It is denoted by/and its unit is hertz $(Hz).$
$\text { Frequency }=\frac{1}{\text { Time period }}$
$\text { Or Time period }=\frac{1}{\text { Frequency }}$
$\text { Frequency }=\frac{1}{\text { Time period }}$
$\text { Or Time period }=\frac{1}{\text { Frequency }}$
