Text Solution

AI Generated Solution

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} ...
