Physics Question from JEE Main 2023 · 24 January, Shift 1

If E⃗\vec{E} represents the electric field vector and K⃗\vec{K} the propagation vector of electromagnetic waves in vacuum, then the magnetic field vector is given by (ω\omega - angular frequency):

  • A

    B⃗=K⃗×E⃗ω\vec{B} = \frac{\vec{K} \times \vec{E}}{\omega}

  • B

    B⃗=ω(E⃗×K⃗)\vec{B} = \omega (\vec{E} \times \vec{K})

  • C

    B⃗=ω(K⃗×E⃗)\vec{B} = \omega (\vec{K} \times \vec{E})

  • D

    (K⃗×E⃗)(\vec{K} \times \vec{E})
