Question

Describe the amplitude , frequency and wavelength,

Answer 1

amplitude is the magnitude of maximum disturbance oin the medium on either side of mean value.
frequency is the number of oscillations completed per unit time.
wavelength is the distance between two consecutive compression and rare action crossing a point

Answer 2

Amplitude -: The maximum displacement of the particles of the medium from their original undisturbed positions, when a wave passes through the medium is called amplitude of the wave. The term amplitude is in fact, used to describe the size of the wave.

Frequency -: The number of complete waves produced in one second is called frequency of the wave. The number of vibrations per second is called frequency. The SI unit of frequency is hertz.

Wavelength -: The minimum distance in which a sound wave repeats itself is called its wavelength. The SI unit of wavelength is metre.
