Explanation of optical phenomena in light of Feynman's Theory

[Wrichik Basu]

In his second lecture of the QED series (see below), Prof. Richard Feynman explains the phenomenon of reflection from a plane mirror, and then the working of a diffraction grating with his theory of arrows (probability amplitudes), and we see that how the new theory, which is much moved from the real world, clearly explains the two phenomena.

But Prof. Feynman does not go into the explanation of other optical phenomena like single and double slit diffraction, though he slightly mentions the single slit diffraction at one point. He says that many of the audience might not know what these phenomena are, and hence, he doesn't complicate his lecture unnecessarily.

I want to have a clear explanation of single slit, double slit and Frensel diffraction in this theory, that is, in terms of probability amplitudes and like the way Prof. Feynman explains the other two phenomena. Can anyone give a proper explanation in light of this theory?

I haven't done the Character of Physical Law series, I'm doing the QED series currently.
