Question

define frequency ,time period, wavelength, vibration ,wave and amplitude

Answer 1

Frequency = The number of vibrations produced by the source of sound wave in one second is called frequency.

Time period = The time taken by a wave to complete one vibration if known as time period.

Wavelength = The length of a wave corresponding to one vibration is known as its wavelength.

Amplitude = The maximum displacement of a wave on wither side of its mean position is called Amplitude.
