An electromagnetic wave going through vacuum is described by `vecE=E_(0)sin(kx-wt) and vecB=B_(0)sin(kx-wt)`. Which of the following equation is true?

`E_(0)k= B_(0)omega`

`E_(0) omega= B_(0)k`

`E_(0)B_(0)= omegak`

None of these

Text Solution

Verified by Experts

The correct Answer is:

As ` c= (E_(0))/(B_(0))`
`implies (omega)/(k)= (E_(0))/(B_(0))implies kE_(0)= omegaB_(0)`
