what are wave length frequency time period amd amplitude of a sound wave?
Answers
Wavelength is the length between two consecutive point in a wave.
Frequency is the no. of cycles made by a wave in a second.
Time period is the time taken by the wave to complete on cycle.
Amplitude is the maximum displacement made by the given wave.
Wavelength:
The distance between two consecutive compressions or two consecutive rarefactions is called the wavelength (λ) of the wave.
It's SI unit is metre.
Frequency:
The number of oscillations of the wave per unit time is called the frequency (n) of the wave. It is also given as the number of compressions or rarefactions that cross us per unit time. Its SI unit is hertz (Hz).
Time period:
The time taken by two consecutive compressions or rarefactions to cross a fixed reference point is called thetime period (T) of the wave.
Amplitude:
The distance between two consecutive compressions or two consecutive rarefactions is called the wavelength (λ) of the wave.
