Question

define frequency, amplitude and wave length and also tell it's unit​

Answer 1

Answer:

Frequency is the number of vibrations experienced by a vibrating body in one second.

Amptitude is maximum extent of vibrations by a vibrating body from its mean position

Wavelength can be defined as the distance between two successive crests or troughs of a wave.

Explanation:

Answer 2

★ Frequency:-

↝ The number of oscillations completed in one second.

↝ SI Unit of Frequency is hertz (Hz).

★ Amplitude:-

↝ The maximum displacement of a wave on either side of its mean position.

↝ SI Unit of Amplitude is meter (m).

★ Wavelength:-

↝ The distance between two consecutive compressions or rarefactions.

↝ SI Unit of Wavelength is meter (m).
