A place for majestic STEMLORD peacocking, as well as memes about the realities of working in a lab.
Rules
- Don't throw mud. Behave like an intellectual and remember the human.
- Keep it rooted (on topic).
- No spam.
- Infographics welcome, get schooled.
This is a science community. We use the Dawkins definition of meme.

Just to point out, because it's bothering me way more than it should...
But the electric and magnetic peaks align with each other's valleys, not with each other's peaks.
If two waves of the same frequency align with each others' valleys, they align with each others' peaks. Do you mean they should be aligned peak to valley? I don't know how you're deciding which direction of the axes is positive and which is negative though.
Uh, no?
No, they fucking shouldn't

Edit: neither of us are right, EM waves in vacuum do travel in phase but in conductors, there is a phase difference between 0° (very high resistance) and 45° (superconductor). So yeah, EM waves can "tell" they're in a dummy load.
Well it's wrong. I suppose you are thinking so because Maxwell's equations shows B depending on (∆E/∆t)[i cant write \partial symbol], BUT remember LHS is not B but is curl(B) so derivative acts on both sides. So they are in phase and not 90° out of phase. So the peaks should align, atleast in free space
Yeah, because it's not pulsing in intensity, it's pulsing between which kind of energy it's being
You're describing circular polarization. It's not the only way.
Maybe it's showing polarization superpositions of the E-field?
