Physics Question from JEE Main 2024 · 30 January, Shift 1

The electric field of an electromagnetic wave in free space is represented as E⃗=E0cos⁡(ωt−kz) i^\vec{E} = E_0 \cos(\omega t - kz) \, \hat{i}. The corresponding magnetic induction vector will be:

  • A

    B⃗=E0Ccos⁡(ωt−kz) j^\vec{B} = E_0 C \cos(\omega t - kz) \, \hat{j}

  • B

    B⃗=E0Ccos⁡(ωt−kz) j^\vec{B} = \frac{E_0}{C} \cos(\omega t - kz) \, \hat{j}

  • C

    B⃗=E0Ccos⁡(ωt+kz) j^\vec{B} = E_0 C \cos(\omega t + kz) \, \hat{j}

  • D

    B⃗=E0Ccos⁡(ωt+kz) j^\vec{B} = \frac{E_0}{C} \cos(\omega t + kz) \, \hat{j}
