Question

Mention five characteristics of sound waves? [5 MARKS]

Answer 1

Characteristic : 1 Mark each

Sound waves are characterized by the following properties:
1. Wavelength : The distance between two consecutive crests of a wave is called Wavelength.

2. Time period : The time taken by the wave to travel one wavelength is called its Time period. Frequency is the reciprocal of time period.

3. Amplitude : The maximum distance travelled by a point of wave from its mean position is called its Amplitude.

4. Mechanical Nature : Sound waves are called mechanical waves since they require a medium for propagation.

5. Longitudinal Nature : Sound waves are vibrations which travel parallel to the direction of propagation of the sound wave.
