The energy of a single photon at the transmitted frequency is 
Answer: Option b
<u>Solution:</u>
Energy of photon is given as 
Where c is the velocity of Light 
h is planck's constant 
λ is the wavelength of photon
Energy of photon can be rewritten as 
Where f is the frequency of photon
Frequency of photon is obtained by dividing velocity of light by wavelength of photon.
