Question

What is the relative phase between E⃗ and B⃗ in a plane electromagnetic wave, and how are they oriented?

G1 Physics · Accepted Answer

Step 1: The electric and magnetic components of a plane EM wave are driven by Maxwell's equations. Step 2: They are perpendicular in space but attain zero, maximum and minimum values simultaneously at a given point. Step 3: Thus E⃗ and B⃗ oscillate in phase and are mutually perpendicular. Option C. Final answer: (C) Same phase; mutually perpendicular.
