To show the nature of the Poynting vector \( \vec{S} \) versus time graph, we will follow these steps: ### Step 1: Define the Poynting Vector The Poynting vector \( \vec{S} \) is defined as: \[ \vec{S} = \frac{1}{\mu_0} \vec{E} \times \vec{B} \] where \( \vec{E} \) is the electric field vector and \( \vec{B} \) is the magnetic field vector. ...
