KCET 2019 | Electromagnetic Waves Question 11 | Physics

An electromagnetic wave is travelling in $$x$$-direction with electric field vector given by, $$\mathbf{E}_y=E_0 \sin (k x-\omega t) \hat{\mathbf{j}}$$. The correct expression for magnetic field vector is

$$\mathbf{B}_y=E_0 C \sin (k x-\omega t) \hat{\mathbf{j}}$$

$$\mathbf{B}_z=E_0 C \sin (k x-\omega t) \hat{\mathbf{k}}$$

$$\mathbf{B}_y=\frac{E_0}{C} \sin (k x-\omega t) \hat{\mathbf{j}}$$

$$\mathbf{B}_z=\frac{E_0}{C} \sin (k x-\omega t) \hat{\mathbf{k}}$$
