What is the intensity of a traveling plane electromagnetic wave if `B_m" is " 3.0xx10^(-4)` T ?

Explanation

To find the intensity of a traveling plane electromagnetic wave given the maximum magnetic field \( B_m = 3.0 \times 10^{-4} \) T, we can follow these steps:

### Step 1: Understand the relationship between intensity, electric field, and magnetic field
The intensity \( I \) of an electromagnetic wave is related to the electric field \( E_m \) and the magnetic field \( B_m \) through the formula:
\[ I = \frac{E_m^2}{2 \mu_0 c} \]
where:
