Question
What is the intensity of a traveling plane electromagnetic wave if $B_{m}$ is $1.0 \times 10^{-4} \mathrm{~T} ?$
Step 1
This relationship is given by the formula: I = (1/2) * μ₀ * c * Bm² where μ₀ is the permeability of free space (4π × 10⁻⁷ T·m/A) and c is the speed of light in a vacuum (3 × 10⁸ m/s). Now, we can plug in the given value of Bm (1.0 × 10⁻⁴ T) into the formula: I Show more…
