Question

13. At the upper surface of the Earth's atmosphere, the time-averaged magnitude of the Poynting vector, ?S? = 1.35 × 10^3 W/m^2, is referred as the solar constant. a) Assuming that the Sun's electromagnetic radiation is a plane sinusoidal wave, what are the magnitudes of the electric and magnetic fields? b) What is the total time-averaged power radiated by the Sun? The mean Sun-Earth distance is R = 1.5 × 10^{11} m.

Step 1

35 x 10^3 W/m^2, we can use the formula: \[ S = \frac{1}{2} E_0 H_0 \] \[ E_0 = \sqrt{\frac{2S}{\mu_0}} \] \[ E_0 = \sqrt{\frac{2 \times 1.35 \times 10^3}{377}} \] \[ E_0 = \sqrt{7.16} \] \[ E_0 = 84.6 \, \text{W/m} \] Show more…

13. At the upper surface of the Earth's atmosphere, the time-averaged magnitude of the Poynting vector, (S) = 1.35 !! 10^3 W/m^2, is referred as the solar constant. a) Assuming that the Sun's electromagnetic radiation is a plane sinusoidal wave, what are the magnitudes of the electric and magnetic fields? b) What is the total time-averaged power radiated by the Sun? The mean Sun-Earth distance is R = 1.5 !! 10^{11} m.
