Question

The rms value of the magnitude of the mag-
netic field in an electromagnetic wave is
0.265 μT.
The speed of light is 3 × 10⁸ m/s and per-
meability of free space is 4π × 10^−7 T · m/A.


Part 1 - Find the rms value is of the electric field.
Answer in units of V/m.

Part 2 - Find average energy density.
Answer in units of nJ/m³.

Part 3 - Find the intensity.
Answer in units of W/m².
