# Sine Wave

Menu Path : **Operator > Math > Wave > Sine Wave**

The **Sine Wave** Operator evaluates an input to generate a value which smoothly oscillates between a minimum and a maximum value. This Operator also includes a frequency value which changes the rate at which the output value oscillates.

If you set **Frequency** to **1**, the output value goes from **Min** to **Max** and back to **Min** as the **Input** changes from **0** to **1**.

You can use this Operator to smoothly move between any two values, for example moving particles up and down. If you set **Min** to **0** and **Max** to **1**, you can use this alongside the [Lerp](Operator-Lerp.md) Operator to interpolate between any two values, like positions or colors.

## Operator properties

| **Input**     | **Type**                                | **Description**                                              |
| ------------- | --------------------------------------- | ------------------------------------------------------------ |
| **Input**     | [Configurable](#operator-configuration) | The value this Operator evaluates to generate the output value. |
| **Frequency** | [Configurable](#operator-configuration) | The rate at which the **Input** value moves between **Min** and **Max**. Larger values make the wave repeat itself more. |
| **Min**       | [Configurable](#operator-configuration) | The minimum value that **Out** can be.                       |
| **Max**       | [Configurable](#operator-configuration) | The maximum value that **Out** can be.                       |

| **Output** | **Type**          | **Description**                                              |
| ---------- | ----------------- | ------------------------------------------------------------ |
| **Out**    | Matches **Input** | The value this Operator generates between **Min** and **Max** based the **Input** and **Frequency**. |

| **Min**       | The value type for the **Min** port. For the list of types this property supports, see [Available types](#available-types). |
| **Max**       | The value type for the **Max** Port. For the list of types this property supports, see [Available types](#available-types). |
