Level 98 🇺🇦Teaching "light as a wave" this week reminded me that most diagrams of electromagnetic (EM) waves use red & blue to distinguish between the electric & magnetic waves.
However, a quick search reveals whether the electric wave is red or blue (and hence the mag wave is the other colour) confirms there's disagreement. So, clearly 😀, an important question for #PhysicsFriday is:
By which colour do you think the electric wave should be represented?
Red
Blue
