Introduction

Consider each of the electric$-$ and magnetic$-$field orientations.

Part A

What is the direction of propagation of the wave if E$=$Ei$^,$B$=$Bj$^$E$=$Ei$^,$B$=$Bj$^.$

Express the direction of the propagation vector, P$$P$,$ as a unit vector. Its three components should be entered in order $($x$,$y$,$z$)$ separated by commas. For example, if the wave propagates only in the $-$x direction, enter $-1,0,0.$
