Amplitude of Wave

Amplitude of Wave

Amplitude is the maximum displacement of particles from their mean position.

### Formula

$$A=y_{max}$$

### Terminologies

- A → Amplitude.

- ymax → Maximum displacement.

### SI Unit

$$m$$

### Conditions / Special Cases

- Energy carried by wave depends on square of amplitude.

$$E\propto A^2$$

### Usage

- Used in energy and intensity calculations.
