Then how do you explain the fact that when low-intensity light
starts shining on a photocell, electrons sometimes appear before
the wave has time classically to transfer a photons-worth of
energy to the photocell? The standard explanation works well:
the photon is as likely to appear in the front of the wave pulse
as at the back.
