Suppose that the electric field part of an electromagnetic wave in vacuum is E={(3.1 N/C) cos [(1.8 rad/m)y+{5.4`xx10^(6)` rad/s} t]} i.
What is the direction of propagation ?

Explanation

(a) `-hat j`
(b) 3.5m,
(c ) 86 MHz,
(d) 100 nT,
`{(100 nT) cos [(1.8" rad/m")y+(5.4xx10^(6)" rad/s")t]} hat K`
