Question

A plane electromagnetic wave propagating along x direction can have following pairs of $ightarrow{E}$and$ightarrow{B}$:

• A. $E_{y}B_{z}$
• B. $E_{z}B_{y}$
• C. $E_{x}B_{y}$
• D. Both (1) and (2)

Answer 1

Answer: (D)

Both (1) and (2)

Answer 2

: As electric and magnetic field vectors $\overrightarrow{E}$and $\overrightarrow{B}$ are perpendicular to each other as well as perpendicular to the direction of propagation of electromagnetic wave. Hence options (1) and (2) are correct.
