## What it models, and when not to use it

No hand-written part: this entry's source has not been written (the docs walk counts it).

## Settings

| Setting | Type | Default | Dimension | Role | Default's kind |
|---|---|---|---|---|---|
| `amplitude` | `float` | `0.4` | none | none declared | none: required |
| `wavenumber` | `Annotated[Quantity, Length ** (-1)]` | `{"unit": "m^-1", "value": 1.3}` | m^-1 | none declared | none: required |

Each role and default's kind is the entry's `setting_roles` (`mime.registry.SettingRole`); a setting that declares none is required.
