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

Text Solution

Verified by Experts

1. Wavelength: The distance between two consecutive compressions or two rarefactions is called the wavelength (a) of sound wave.
2. Frequency: The number of waves produced per unit time for per second) is called the frequency (v) of the sound wave.
OR Number of compressions or rarefactions that cross a fixed point per unit time is called the frequency (V) of sound wave.
3. Time period : The time taken by two consecutive compressions or two rarefactions to cross a fixed point is called the time period (T) of the sound wave.
4. Amplitude : The magnitude of the maximum disturbance in the medium on either side of the mean value is called the amplitude (A) of the sound wave.
