  • Suppose that the electric field part of an electromagnetic wave in vacuum is E is equal to {(3.1 N/C) cos [(1.8 rad/m) y plus (5.4 × 106 rad/s)t]}ˆi . What is the direction of propagation?

11) Suppose that the electric field part of an electromagnetic wave in vacuum is E = \left \{ ( 3.1 N/C )\cos [ ( 1.8 rad /m)y + ( 5.4 \times 10 ^6 rad /s t )] \right \} \hat i
(a) What is the direction of propagation?

E = \left \{ ( 3.1 N/C )\cos [ ( 1.8 rad /m)y + ( 5.4 \times 10 ^6 rad /s t )] \right \} \hat i

E = \left \{ ( 3.1 N/C )\sin [ (\frac{\pi }{2}-(( 1.8 rad /m)y + ( 5.4 \times 10 ^6 rad /s t ))] \right \} \hat i

The electric field vector is in the negative x-direction and the wave propagates in the negative y-direction.
