This is insanely clear. The best part of the explaination is that it sticked to itself from the start as best it could, having very little stretching to the far out of the topic (as most science videos tends to be in order to be accurate). One the best example videos of ELI5 kind of things. I am saving this for future refrence 😁👍

Because light is not a wave - it's a particle with probability distribution. In classical electrodynamics, the Maxwell model is perfectly fine. It utterly breaks if you achieve quantum effects, like the photoelectric effect. Energy is not continuous across space anymore - it's quantized. We've also seen this in the famous Young Double Slit experiment when it was performed with individual electrons or photons. The particle's behave probabilistically.

Think of a rock being dropped into a pool of water. The waves radiate out from the centre. Now imagine that a tiny surfer is surfing one of the waves. He will move out from the centre in a straight line. Similarly, a light bulb radiates light out in all directions. But individual photons each follow their own path radiating outwards from the centre like the spokes of a bicycle wheel. As for explanations of the wave / particle duality, quantum effects and so forth, I'll leave that to the experts! Oh, and as a wee aside it is worth mentioning that Albert Einstein was a big fan of Maxwell (even if his equations needed polishing). Though to be honest I may just be mentioning this because I am a little biased in Maxwell's favour. I had the pleasure of visiting the residence that was his birthplace and is now a museum a number of years back (during the Edinburgh Science Festival). We were treated to a talk on his life and achievements. It is a shame that he is not revered more. Even in his country of birth, few other than those with an interest in physics know about him and yet his Wikipedia entry has besides the entry for "Influenced:" the words "Virtually all subsequent physics". Indeed, were it not for Maxwell I might very well not have had this device to tap my thoughts into or a means by which to communicate them to just about any inhabited part of the planet. That's quite a thought!

That explanation with the radio tower and how the field arrows stay in place is the best I've seen for this subject. I feel like I understand it much better now.
