easy · MCQ · Q-7B6337
In an electromagnetic wave propagating through vacuum, the electric field, the magnetic field and the direction of propagation are:
- A.All parallel to one another
- B.Mutually perpendicular to one anotherCorrect answer
- C.E and B parallel, both perpendicular to propagation
- D.E along propagation, B perpendicular
Solution
EM waves are transverse; think of E x B giving the direction of travel.
