Question

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

Answer 1

Explanation:

Time period: The time taken by two consecutive compressions or rarefactions to cross a fixed reference point is called the time period (T) of the wave. Amplitude: The magnitude of the maximum disturbance in the medium on either side of the mean value is called the amplitude of the wave.

Answer 2

• $\large\tt\red{WAVELENGTH→}$ Wavelength can be defined as the distance between two consecutive rarefactions or two consecutive compressions. The SI unit of wavelength is meter (m).

• $\large\tt\red{FREQUENCY→}$ Frequency is defined as the number of oscillations per second. The SI unit of frequency is hertz (Hz).

• $\large\tt\red{TIME PERIOD→}$ Amplitude can be defined as the maximum height reached by the trough or crest of a sound wave.

• $\large\tt\red{AMPLITUDE→}$ The time period is defined as the time required to produce one complete cycle of a sound wave.
