The intensity of sunlight striking Earth's upper atmosphere is approximately 1.35 × 10^3 W/m^2. a. Calculate Emax at this location assuming a single sinusoidal electromagnetic wave. Express your answer to three significant digits and include the appropriate units. b. Calculate Bmax at this location assuming a single sinusoidal electromagnetic wave. Express your answer to three significant digits and include the appropriate units. c. Given that Earth is 1.5 ×× 101111 mm from the Sun, what is the power output of the Sun? Express your answer to two significant digits and include the appropriate units. d. If all the sunlight that strikes the upper atmosphere reached Earth's surface, how many watts of power would reach Earth's surface? (Hint: The Earth-Sun distance is so great that you can assume all the sunlight is perpendicular to the cross-section of Earth.) Express your answer to three significant digits and include the appropriate units.
