Question

what do u understand by Amplitude​

Answer 1

$\green\bigstar\blue{\bold{\underline{\underline{Answer}}}}$

Amplitude, in physics, the maximum displacement or distance moved by a point on a vibrating body or wave measured from its equilibrium position. It is equal to one-half the length of the vibration path. The amplitude of a pendulum is thus one-half the distance that the bob traverses in moving from one side to the other. Waves are generated by vibrating sources, their amplitude being proportional to the amplitude of the source.

For a transverse wave, such as the wave on a plucked string, amplitude is measured by the maximum displacement of any point on the string from its position when the string is at rest. For a longitudinal wave, such as a sound wave, amplitude is measured by the maximum displacement of a particle from its position of equilibrium. When the amplitude of a wave steadily decreases because its energy is being lost, it is said to be damped.

Answer 2

★ What is Amplitude?

→ The amplitude of a periodic variable is a measure of its change in a single period. In older texts, the phase of a period function is sometimes called the amplitude.

Or we can say in simple words :-

The maximum displacement of a vibrating object from its Central position is called the amplitude of vibration.

→ There are various definitions of amplitude, which are all functions of the magnitude of the differences between the variable's extreme values.

Formula :-

→ x = A sin(w[ t - k]) + b

Here,

• x = Osillating variable.
• A = Amplitude.
• w = Angular frequency.
• t = time.
• k = Arbitrary constant representing time offset.
• b = Arbitrary constant representing displacement offset.
