The magnetic field of a plane electromagnetic wave is given by B⃗ = 2 × 10⁻⁸ sin(0.5 × 10³ x + 1.5 × 10¹¹ t) ȷ̂ T. The amplitude of the electric field would be

Question

Accepted Answer

(3) 6 V m⁻¹ along z-axis. E₀ = cB₀ = 3 × 10⁸ × 2 × 10⁻⁸ = 6 V m⁻¹ phase (kx + ω t) ⇒ propagation along -ı̂; B̂ = ȷ̂ -ı̂ = Ê × ȷ̂ ⇒ Ê = k̂, since k̂ × ȷ̂ = -ı̂
