At the top of Earth’s atmosphere, the time-averaged Poynting vector associated with sunlight has a magnitude of about 1.4 kW/m2. (a) What are the maximum values of the electric and magnetic fields for a wave of this intensity? (b) What is the total power radiated by the sun? Assume that the Earth is 1.5 × 1011 m from the Sun and that sunlight is composed of electromagnetic plane waves.
