Question

Define these:- Vibration, Frequency, Amplitude, Audible Frequencies.​

Answer 1

Answer:

Vibration:- Vibration is a machanical phenomenon whereby Oscillation occur about an equilibrium point.

Frequency:- the number of oscillation of vibration per second is called the frequency of oscillation.

Amplitude:- the maximum distance to which a vibrating body moves on idle side of its mean position is called the amplitude of vibration.

Audible frequency:- for human range of audible frequency is roughly from 20 to 20000 Hz.

Answer 2

$\large{\sf{\underline{\underline\red{Answer!!}}}}$

• Vibration: The to and fro or back and forth motion of an object is called vibration.

• Frequency: The number of oscillations produced by a vibrating body in one  second is called frequency. It is expressed in a unit called hertz (Hz).

• Amplitude: the maximum displacement of a vibrating body from its mean  position is called amplitude.
