Question

In a travelling plane electromagnetic wave , the maximum magnetic field is 1.26×10^-6 T. The intensity of the wave is (Assume u0=1.26×10^-6 H/m)
​

Answer 1

Answer:

Explanation:For an electromagnetic wave, you can find its intensity by computing the magnitude of the Poynting vector, and in most circumstances taking its time average. For a plane wave and using SI units, the time-averaged intensity comes out to 12cϵ0E20 where E0 is the peak electric field.
