Question

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

Answer 1

$\sf\red{\boxed{(a) Wavelength–}}$ Wavelength can be defined as the distance between two consecutive rarefactions or two consecutive compressions. The SI unit of wavelength is meter (m).

$\sf\green{\boxed{(b) Frequency – }}$Frequency is defined as the number of oscillations per second. The SI unit of frequency is hertz (Hz).

$\sf\pink{\boxed{(c) Amplitude –}}$ Amplitude can be defined as the maximum height reached by the trough or crest of a sound wave.

$\sf\orange{\boxed{(d) Time\:period – }}$The time period is defined as the time required to produce one complete cycle of a sound wave.

(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.
