Text Solution

Verified by Experts

Wavelength : Distance between two consecutive compressions of rarefactions , denoted by 1, unit is metre .
Frequency : Number of oscillations per unit time, it.s unit is Hertz (Hz) denoted by .f..
Time period : Time taken for the wave (disturbance of compressions and rarefactions) denoted by T, unit is second.
Amplitude : the magnitude of maximum displacement in the medium from mean position.
