The wavelength of a yellow line in spectrum of sodium atom is 5896 A. Express it in nm.

Explanation

To convert the wavelength of the yellow line in the spectrum of a sodium atom from angstroms (A) to nanometers (nm), we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Conversion Factors**:
- 1 angstrom (A) = \(10^{-10}\) meters (m)
- 1 nanometer (nm) = \(10^{-9}\) meters (m)
