Question

In vecE and vecK represent electric field and propagation vectors of the EM waves in vacuum, then magnetic field vector is given by: (ω- angular frequency): (A) (1/ω)( barK × barE) (B) ω( overline K × overline E ) (C)  barK × barE (D) ω( overline E × overline K )

Magnetic field vector will be in the direction of hat K × hat E magnitude of B =( E / C )=( K /ω) E Or B =(1/ω)( K × E )

Q. In $E$ and $K$ represent electric field and propagation vectors of the EM waves in vacuum, then magnetic field vector is given by: $(ω -$ angular frequency):

$\frac{1}{ω} (\overset{ˉ}{K} \times \overset{ˉ}{E})$

$ω (\overline{K} \times \overline{E})$

$\overset{ˉ}{K} \times \overset{ˉ}{E}$

$ω (\overline{E} \times \overline{K})$

Magnetic field vector will be in the direction of $\hat{K} \times \hat{E}$
magnitude of $B = \frac{E}{C} = \frac{K}{ω} E$
Or $B = \frac{1}{ω} (K \times E)$

Q. In E and K represent electric field and propagation vectors of the EM waves in vacuum, then magnetic field vector is given by: (ω− angular frequency):
