Reference no: EM13550321

Light from the sun arrives at the earth, an average of 1.50×1011 m away, at the rate of 1.40×103 W/m2, for an area perpendicular to the direction of the light. Approximate sunlight as monochromatic with a frequency of 5.17×1014 Hz. How many photons fall per second on each square meter of the earth's surface directly facing the sun? What is the power output of the sun? How many photons per second does it emit? How many photons per cubic meter are there near the earth?
