A plane electromagnetic wave is travelling along +y-axis. The value of electric field at a point is →E=12.3ˆiNC The magnitude and direction of magnetic field B at this point is:
Options:
4.1×10−8T, along -z axis
4.1×10−8T, along +z axis
36.9×108T, along -z axis
12.3 T, along +z axis
Correct Answer:
4.1×10−8T, along -z axis
Explanation:
The correct answer is Option (1) → 4.1×10−8T, along -z axis
