`A` sodium street light gives off yellow light that has a wavelength of `589nm`. What is the frequency of this light?

Explanation

To find the frequency of the yellow light emitted by a sodium street light with a wavelength of 589 nm, we can use the relationship between frequency (ν), wavelength (λ), and the speed of light (c). The formula is given by:

\[ \nu = \frac{c}{\lambda} \]

### Step-by-Step Solution:

1. **Identify the given values**:
- Wavelength (λ) = 589 nm
