Question
The Sun delivers an average power of $1370 . \mathrm{W} / \mathrm{m}^{2}$ to the top of Earth's atmosphere. Find the magnitudes of $\overrightarrow{\mathrm{E}}_{\max }$ and $\overrightarrow{\mathrm{B}}_{\max }$ for the electromagnetic waves at the top of the atmosphere.
Step 1
The average intensity is given by $I = \frac{1}{2} \epsilon_0 c E_{\max}^2$, where $\epsilon_0$ is the permittivity of free space, $c$ is the speed of light, and $E_{\max}$ is the maximum electric field strength. Show more…
