Question
A magnetic field vector in an electromagnetic wave is represented by $$ \stackrel{\otimes}{B}=B_0 \sin \left(2 \pi v t-\frac{2 \pi x}{\lambda}\right) \hat{j} $$ Its associated electric field vector is $\_\_\_\_$。
Select the correct option:
A
$\stackrel{\otimes}{E}=-v \lambda B_0 \sin \left(2 \pi v t-\frac{2 \pi x}{\lambda}\right) \hat{k}$
B
$\stackrel{\otimes}{E}=v \lambda B_0 \sin \left(2 \pi v t-\frac{2 \pi x}{\lambda}\right) \hat{k}$
C
$\stackrel{\otimes}{E}=-v \lambda B_0 \sin \left(2 \pi v t-\frac{2 \pi x}{\lambda}\right) \hat{i}$
D
$\stackrel{\Delta}{E}=v \lambda B_0 \sin \left(2 \pi v t-\frac{2 \pi x}{\lambda}\right) \hat{i}$
