Nature of electromagnetic wave

Question

A plane electro magnetic wave is propagating in free space. Then select the correct option

Easy

A

Direction of propagation is same as the direction of $\vec{E} .$
B

Direction of propagation is same as the direction of $\vec{B} \times \vec{E}$
C

$\frac{E}{B} = \frac{1}{\sqrt{μ_{0} ε_{0}}}$
D

$\frac{E}{B} = \sqrt{μ_{0} ε_{0}}$

Solution

(3)
Direction of propagation is same as the direction of $\vec{E} \times \vec{B}$
$\frac{E}{B} = e = s p e e d o f l i g h t = \frac{1}{\sqrt{μ_{0} ε_{0}}}$
