Question

waht are wavelength frequency, time period and amplitude of a sound​

Answer 1

Answer:

a) Wavelength: The distance between two consecutive compressions or two consecutive rarefactions is known as the wavelength. Its SI unit is metre (m).

(b) Frequency: The number of complete oscillations per second is known as the frequency of a sound wave. It is measured in hertz (Hz).

(c) Amplitude: The maximum height reached by the crest or trough of a sound wave is called its amplitude.

(d) Time period: Time taken for one complete cycle of vibration to pass a given point. As the frequency of a wave increases, the time period of the wave decreases. The unit for time period is 'seconds'.

Answer 2

wavelength:-

The distance over which the wave's shape repeats is known as wavelength.

frequency:-

Frequency is number of vibrations produced per second.

time period:-

The time taken for one complete oscillation in the density of the medium is called the Time Period .

amplitude:-

The amplitude of a sound wave is the measure of the height of the wave. The amplitude of a sound wave can be defined as the loudness or the amount of maximum displacement of vibrating particles of the medium from their mean position when the sound is produced. It is the distance between crest or trough and the mean position of the wave.
