Question

Which of the following statements correctly describes the orientation of the electric field E, the magnetic field B, and the velocity of propagation v of an electromagnetic wave?
a. E is perpendicular to B; v may have any orientation relative to E
b. E is perpendicular to B; v may have any orientation perpendicular to E
c. E is perpendicular to B; B is parallel to v
d. E is perpendicular to B; E is parallel to v
e. E is parallel to B; v is perpendicular to both E and B
f. Each of the three vectors is perpendicular to the other two

Explanation / Answer

Both the electric field and the magnetic field are perpendicular to the direction of travel x

so your answer is

f. Each of the three vectors is perpendicular to the other two
