Yes, that looks right. It has been around almost 6 years ago since I did this in 6th form. Was going to mention about photons and narrow slits experiment.

Re: The Nature of Light
Right, the only element missing is how String Theory impacts on Quantum Electrodynamics. Thats when things get interesting.

Re: The Nature of Light
I deliberately left out string theory since:
1) It is currently untested (and in fact untestable) and therefore more along the lines of a group of interesting potential lines of enquiry rather than a single coherent theory, and
2) It is primarily an attempt to resolve issues in quantum gravity rather than some unexplained aspect of light. As far as I am aware QED already provides a comprehensive description of the latter to within current experimental precision.
I did try to just give an outline of the increasingly sophisticated models of light rather than a full overview of the development of modern physics, although I seem to have ended up covering rather a lot of it anyway.
Re: The Nature of Light
Yep, nor is the string 'theory' a 'theory'. Just an untested hypothesis.
