Can you justify why this fact is not dependent on your choice of gauge?

Would you be willing to answer another question of mine related to the geometry of $E$ and $B$ for plane waves? physics.stackexchange.com/questions/173496/…

Doesn't this depend on an arbitrary choice of $\mathbf{A}$? (Refer to physics.stackexchange.com/questions/173499/…)

This doesn't address my question. Can you modify your answer?

comment What is the direction of the magnetic vector potential in an electromagnetic plane wave?
In specifying that plane wave solution, aren't you choosing $\mathbf{A}$ to be perpendicular to $\mathbf{k}$?

Yes, phasors fall under that category

comment Does a time-varying intensity contribute to the photoelectric effect?
By rapidly varying, I mean time varying. I'm asking if time varying intensity contributes to the energy that induces electron emission.

comment Does a time-varying intensity contribute to the photoelectric effect?
Then let's consider low intensities that vary rapidly. Does time-variance of (low) intensity contribute to the energy of the light and induce electron emission?
