calculate the mass of a photon with wavelength 3.6 A

Explanation

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

### Step 1: Convert Wavelength to Meters
First, we need to convert the wavelength from angstroms to meters. We know that:
1 angstrom (Å) = \(1 \times 10^{-10}\) meters.

So, for a wavelength of 3.6 Å:
\[
