The solar constant is the radiant flux density (irradiance) from the Sun at the surface of the Earth's atmosphere and is about 0.135 W/m². Assume an average wavelength of 700 nm for the sun's radiation that reaches the Earth. Find (a) the amplitude of the E-field and B-field, (b) the number of photons that arrive each second on each square meter of a solar panel, and (c) a harmonic wave equation for the E-field of the solar radiation, inserting all constants numerically.
