How did maxwell conclude light was an electromagnetic wave? so maxwell had a few different arguments for why light is an electromagnetic wave.
00:11
So the first argument could be that maxwell could not imagine waves that propagate in an empty space.
00:19
So this electromagnetic wave had to have some medium that fills a space.
00:26
So for this electromagnetic wave, he had to assume the existence of some medium that fills a space.
00:34
So let's just say some medium fills up empty space.
00:43
Then what maxwell does next, he derives the speed of propagation of electromagnetic waves, not only in vacuum, but in different substances.
00:54
So he derives the speed of propagation.
00:57
So he derives the speed of propagation of the waves.
01:06
And not only in one medium, he does this for multiple different mediums...
