Question

What are wavelength, frequency, time period and amplitude of a sound wave?​

Answer 1

Answer:

Frequency : The number of oscillations made by the wave in one second is called the frequency of the wave. 3. Time period : The time taken by the wave to complete one oscillation is called the amplitude of the wave.

Answer 2

Answer:

(a) Wavelength – Wavelength can be defined as the distance between two consecutive rarefactions or two consecutive compressions. The SI unit of wavelength is meter (m).

(b) Frequency – Frequency is defined as the number of oscillations per second. The SI unit of frequency is hertz (Hz).

(c) Amplitude – Amplitude can be defined as the maximum height reached by the trough or crest of a sound wave.

(d) Time period – The time period is defined as the time required to produce one complete cycle of a sound wave.
