Question

what are wavelength, frequency, time period and amplitude of sound waves?

Answer 1

Here is your answer.......
.
◻Amplitude : The maximum displacement of the particles of medium from their original position is called the amplitude of the wave. It is represented by (A). The SI unit of amplitude is metre.
.
◻Wavelenght : The minimum distance in which the sound wave repeats itself, is called its wavelength. It is represented by Lambda. The SI unit is metre.
. \
Lambda (sign) = / \ (Join the lines)
.
◻Time Period : The time require to produce 1 cycle or 1 complete wave, is called the time period of the wave. It is repesented by (T). The SI unit is second (s).
.
◻Frequency : The number of wave or cycles (complete waves) produce in one second, is called frequency of the wave. It is represented by (f). The SI unit is Hertz (Hz)..

Answer 2

Explanation:

The period of a wave is the time it takes to complete one cycle. The frequency is just the opposite; it's the number of wave cycles that are completed in one second. Amplitude and wavelength are both measures of distance. The amplitude measures the height of the crest of the wave from the midline
