The electric field and magnetic field components of an electromagnetic wave going through vacuum is described by Ex = E₀sin (kz - ω t) By = B₀sin (kz - ω t) Then the correct relation between E ₀ and B ₀ is given by (a) E₀ B₀ = ω k (b) E₀ = k B₀ (c) k E₀ = ω B₀ (d) ω E₀ = k B₀

Answer: (c). Wave speed c = (ω)/(k) and E₀ = cB₀. E₀ = (ω)/(k)B₀ ⇒ kE₀ = ω B₀. So the answer is (c).
