calculate the mass of a photon with wavelength 3.6 A

Explanation

To calculate the mass of a photon with a given wavelength of 3.6 Å (angstroms), we can follow these steps:

### Step 1: Convert Wavelength to Meters
The wavelength is given in angstroms, which needs to be converted to meters for calculation.

\[ 1 \, \text{Å} = 10^{-10} \, \text{m} \]
