The magnetic field of a plane electromagnetic wave propagating along the z -direction in a vacuum is given by 
. The electric field 
, at the moment 
is: (All quantities are in SI unit)
A
B
C
D
Text Solution
Verified by ExpertsThe correct answer is:
D
The magnetic field is given by
.
At 
.
Since 
, the magnitude of the electric field at 
will be
.
The wave is propagating along the 
direction and the magnetic field 
is in the 
direction (positive 
direction)
∴ The direction of 
is
