Question 108: EM waves

Question

In an electromagnetic wave the electric field vector and magnetic field vector are given as $$\overrightarrow E  = {E_0}\widehat i$$ and $$\overrightarrow B  = {B_0}\widehat k$$ respectively. The direction of propagation of electromagnetic wave is along :

Accepted Answer

Direction of propagation = $$\overrightarrow E  	imes \overrightarrow B  = \widehat i 	imes \widehat k =  - \widehat j$$

Answer

$$\left( {\widehat k} \right)$$

Answer

$$\widehat j$$

Answer

$$\left( { - \widehat k} \right)$$

Answer

$$\left( { - \widehat j} \right)$$
