I am not a physicist but fun fact, In transit there is no such thing as a photon(electro magnetic waves can transit at any energy level) however light can only interact with matter at discrete energy levels, so the photon(a discrete energy level of light) only exists there, at the interaction with matter.
For some very good practical optics you can do a lot worse than the Huygens Optics youtube channel.

- BlueTemplar 4y agoParticle and waves were just two seemingly incompatible models the modern natural philosophers used. In post-modern (quantum) physics and the discovery/conception of photons by Einstein, they have been brought together as the same concept (and more generally for non-light by de Broglie as quantons). A wavepacket is probably a good way to think of single quantons : https://upload.wikimedia.org/wikipedia/commons/9/92/Wavelet.gif https://upload.wikimedia.org/wikipedia/commons/9/92/Wavelet....
