The table shows information about the wavelengths of different colours of light in a vacuum:
| Colour of light | Wavelength / nm\text{nm}nm |
|---|---|
| violet | 400 |
| blue | 460 |
| yellow | 580 |
| red | 660 |
Using the data, what is a likely wavelength for green light?
430 nm430\text{ nm}430 nm
530 nm530\text{ nm}530 nm
610 nm610\text{ nm}610 nm
690 nm690\text{ nm}690 nm
