Although photons and mechanical waves obey the same wave equation, the electric field envelope of a single photon propagating in a vacuum is fixed and does not change with propagation.
Although photons and mechanical waves follow the same fluctuating equations, the electric field envelope of individual photons propagation in a vacuum is fixed and does not change with propagation.
