An electromagnetic wave in vacuum has the electric and magnetic field `vecE` and `vecB`, which are always perpendicular to each other. The direction of polarization is given by `vecX` and that of wave propagation by `vecK`. Then

Options

A. `vecX|\|vecB` and `veck|\|vecBxxvecE `
B. `vecX|\|vecE`and `veck|\|vecExxvecB`
C. `vecX\|vecB` and `veck|\|vecExxvecB`
D. `vecX|\|vecE` and veck|\|vecBxxvecE`

Answer

B

Explanation

`:'` The E.M. wave are transverse in nature i.e.,
`=(veckxxvecE)/(muomega)=vecH`....(i)
where `vecH=(vecB)/(mu)`
and `(veckxxH)/(omegaepsilon)=-vecE`...(ii)
`veck` is `bot` `vecH` and `veck` is also `bot` to `vecE`
or In other words `vecX|\|vecE` and `veckk|\|vecExxvecB`
