The wavelength of a light is of the order of `6400 Å`. Express this in micron and metre.

Explanation

To convert the wavelength of light from angstroms to microns and meters, we can follow these steps:

### Step 1: Understand the given information
We are given that the wavelength of light is \( 6400 \, \text{Å} \) (angstroms).

### Step 2: Convert angstroms to meters
1 angstrom is equal to \( 10^{-10} \) meters. Therefore, to convert angstroms to meters, we can use the conversion factor:
