Calculate the mass of a photon of sodium light having wavelength `5894 Å` and velocity `3 xx 10^8 ms^(-1). (h = 6.6 xx 10^(-34) kg m^2 s^(-1))`

Explanation

To calculate the mass of a photon of sodium light with a wavelength of `5894 Å` (angstroms) and a velocity of `3 x 10^8 m/s`, we will use the formula that relates the mass of a photon to its wavelength and velocity.

### Step-by-Step Solution:

1. **Convert Wavelength to Meters:**
The given wavelength is in angstroms. We need to convert it to meters.
\[
1 \text{ Å} = 10^{-10} \text{ m}
