## What is the amplitude?

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.

**What is the amplitude on a diagram?**

The amplitude ( ) of a wave is the distance from the centre line (or the still position) to the top of a crest or to the bottom of a trough . Be careful with this quantity – the centre line is not always given in a diagram. Amplitude is measured in metres ( ).

### What is a amplitude example?

Here are some examples of amplitude: The amplitude of a water wave would be the distance between the top of a wave and the surface of the water at rest. The amplitude of a sound wave would be the density of air particles at the center of a compression or pulse of sound.

**What is amplitude of sound?**

Amplitude of Sound. �The strength or level of sound pressure. The number of molecules in the sound wave in b is greater than the number in the sound wave in a, therefore the amplitude of the sound wave in b is greater. Measuring Amplitude.

## What is the symbol of amplitude?

The symbol for amplitude is A (italic capital a). The SI unit of amplitude is the meter [m], but other length units may be used.

**What is unit of amplitude?**

SI unit of amplitude is metre (m) as amplitude is the maximum displacement suffered by the particles of the medium from their mean positions during the wave propagation. SI unit of displacement is metre. so, SI unit of amplitude is metre.

### What is an amplitude look like in a graph?

Sketch the graph of y = sin x from –4π to 4π,as shown in this figure.

**What is an antonym of amplitude?**

## What is the formula of amplitude?

The amplitude formula is also expressed as the average of the maximum and minimum values of the sine or cosine function. i.e., Amplitude = (max + min) / 2. What are the Units of an Amplitude Formula? The unit in an amplitude formula is the meter (m). The amplitude of a wave is the maximum disturbance or displacement of the medium from the

**What is the simple definition of amplitude?**

The definition of amplitude refers to the length and width of waves, such as sound waves, as they move or vibrate. How much a radio wave moves back and forth is an example of its amplitude.
