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/cm2. Assume an average wavelength of 700 nm for the sun’s radiation that reaches the earth. Find (a) the amplitude of the - and -fields; (b) the number of photons that arrive each second on each square meter of a solar panel; (c) a harmonic wave equation for the -field of the solar radiation, inserting all constants numerically.
