Light as a wave, which wave is the "correct" wave?
Okay so when describing light as a wave, I get two different images depending on what I am looking at.
So when I am looking Young's double slit experiment I see light as "wave fronts" like in this picture:

But in the photoelectric effect light is show as this type of wave:

So when talking about light as a wave, which wave is the "correct" wave? I ask this because the photoelectric effect shows why light isn't a wave but if you use the "wave fronts" light then there doesn't seem to be a problem.
My second question. When light is shone through a single slit, you get a maxima in the middle and some other maxima like this:

How can this be explained using phasor arrows where the photons don't interfere with themselves?
