Question

What is Amplitude? Explain​

Answer 1

$\huge\underbrace\mathfrak\pink{Answer:-}$

Sound is a form of energy that is produced by vibrating bodies. It requires a medium for its propagation. Hence, sound cannot propagate in a vacuum as there will be no material to transfer sound waves. The back and forth motion of an object due to which sound is produced is known as sound vibration. It is also known as oscillatory motion. The regular rhythmic back and forth movement is referred to as the oscillation.

The amplitude of a sound wave is the measure of the height of the wave. The amplitude of a sound wave can be defined as the loudness or the amount of maximum displacement of vibrating particles of the medium from their mean position when the sound is produced. It is the distance between crest or trough and the mean position of the wave.

Amplitude of sound

Loudness is directly proportional to the amplitude of the sound. If the amplitude of a sound wave is large, then the loudness of sound will be more. If the amplitude is small, then the sound will be feeble.

Hope it helps you :)

Answer 2

Answer:

The maximum distance moved by a particle from the mean position or central position in a vibrational motion is called Amplitude.
