If electric field

E=E_0 \sin (\omega t-k z) \hat{i}

and magnetic field

B=B_0 \sin (\omega t-k z) \hat{j},

then electromagnetic wave travels along

View answer and explanation

Correct option: A

+z

direction

Option A (+z direction) is correct because the direction of propagation of an electromagnetic wave is given by the direction of

\vec{E} \times \vec{B}

.
