Question

If the magnetic field of an electromagnetic wave is in the +-direction and the electric field of the wave is in the +-direction, the wave is traveling in the

-x-direction. |

-y-direction. |

+z-direction. |

xy-plane. |

-z-direction. |

Answer #1

Then in Electromagnetic wave the electric field & magnetic
field are mutually perpendicular to the direction of propagation of
the wave.

Poynting vector is ,

S = (1/mu_o) E X B

X represents -- cross product of E and B

curl our right hand fingers from E to B then our thumb indicates
the direction of the motion of the wave.

So,

curl our fingers from + to +,

curl our fingers from +y to +x , then my right thumb points in -z direction.

the wave is traveling in the... xy -plane.

then the answer is xy- plane.

Then second last (d) option is correct .

I hope help you !!
