Physics · JEE | Electromagnetic Waves

In a plane electromagnetic wave propagating along the \( z \)-direction, the electric field is given by \( E_x = E_0 \sin(kz - \omega t) \). The corresponding magnetic field \( B_y \) is given by:

1. A
   \( B_y = -B_0 \sin(kz - \omega t) \)
2. B
   \( B_y = B_0 \sin(kz - \omega t) \)
3. C
   \( B_y = B_0 \cos(kz - \omega t) \)
4. D
   \( B_y = \frac{E_0}{c} \cos(kz - \omega t) \)
