The electric field oscillation of a beam of light is given by: $$ E = E_o \sin(kx-2\pi ft) $$ Energy of every photon in this case would be $E_p = hf$ since the frequency of oscillation is $f$.
By equating the total intensity of light in terms of the electric field and in terms of energies of indivisual photons, we can find the number of photons crossing a unit area per unit time. Let this number be $n_p$.
I wanted to ask if I can consider the whole beam of light to be composed of indivisual beams with each beam having one photon per unit time per unit area and also them being in the same phase. If I can, then the the maximum electric field oscillation of each such beam should be $\frac{E_o}{n_p}$.
