4-52. Light from the sun arrives at the earth at the rate of about 1400 W/m² of area perpendicular to the direction of the light. Assuming that sunlight consists exclusively of light of wavelength 6x107 m, find the number of photons per second that fall on each square meter of the earth's surface directly facing the sun.
