Physics · Electromagnetic Waves
Which of the following vector equations shows that electromagnetic waves are transverse in nature? (Where k̄ is the wave vector, Ē is the electric field vector, and H̄ is the magnetic field intensity vector)
- 1∇ • Ē = ρ / ε0
- 2k̄ • Ē = 0 and k̄ • H̄ = 0✓
- 3k̄ × Ē = 0 and k̄ × H̄ = 0
- 4S̄ = Ē × H̄
Correct answer
k̄ • Ē = 0 and k̄ • H̄ = 0
