Electromagnetic Waves question

2002 · Q137

NEETPhysicsElectromagnetic WavesMCQ+4 / −1
The velocity of electromagnetic wave is parallel to
  1. A
    B→×E→\overrightarrow B \times \overrightarrow EB×E
  2. B
    E→×B→\overrightarrow E \times \overrightarrow BE×B
  3. C
    E→\overrightarrow EE
  4. D
    B→\overrightarrow BB
View written solutionFree

Correct answer: B

Since, the direction of propagation of electromagnetic waves is perpendicular to Electric field and Magnetic field. Also electric and magnetic fields perpendicular so, direction of the wave will be parallel to E→×B→\overrightarrow E \times \overrightarrow B E×B.
