Only some humans can see this type of light

Awesome video. However I have to clear something up; hi, electrical engineer here, electromagnetic waves look nothing like the one flat plane of electric up/down wigglies perpendicular to the one flat plane of magnetic side/side wigglies. The problem with that god damned chart and representation is that it's easy to grasp onto when you aren't familiar with the topic, and all media grabbed onto it at the expense of the larger picture. What that chart is *representing* is the *change* in the *amplitude* (intensity) over *time* of each of the types of waves,  and for *mathematical convenience* they are shown perpendicular to each other, as the fall in intensity of one type of wave inspires the rise in intensity of the other and vice-versa. What it does show well is the fact that it is self-propagating with no loss as it goes along through the medium it's travelling through. So, trying to picture light waves as + shaped wigglies is really useless when trying to imagine how polarization factors in; really, it's hard to say what it DOES look like, but I had to clear up a widespread misconception about what that specific graphical representation is displaying. Here's something closer to what it probably looks like - https://aiweirdness.com/post/80108400183/light-in-a-circular-cavity-makes-a-variety-of
