> The frequency at which the suspension spring oscillates.

## Definition

* **Type:** Property
* **Namespace:** [UnityEngine](/engine/6000.5/script-reference/unityengine.md)
* **Assembly:** UnityEngine.Physics2DModule

```csharp
public float frequency { get; set; }

### Remarks

The suspension spring will oscillate with a certain frequency as forces are added and removed from it.  A *damping ratio* can be set to cause this oscillation to die down over time.
