In a plane electromagnetic wave, the directions of electric field and magnetic field are represented by k ^ and 2 i ^ - 2 j ^ , respectively. What is the unit vector along direction of propagation of the wave.

Question

In a plane electromagnetic wave, the directions of electric field and magnetic field are represented by k ^ and 2 i ^ - 2 j ^ , respectively. What is the unit vector along direction of propagation of the wave., 1 2 ( i ^ + j ^ ), 1 2 ( j ^ + k ), 1 5 ( i ^ + 2 j ^ ), 1 5 ( 2 i ^ + j ^ )

E → × B → ‖ C → E ^ × B ^ = 1 2 i ^ j ^ k ^ 0 0 1 1 - 1 0 = i ^ + j ^ 2 ⇒ c ^ = i ^ + j ^ 2
