The Solar Constant

  1. Jan 20, 2007 #1
    Assume that a perfect reflector of 1 square metre, is sent up in space and aligned to reflect the light from sun to earth. How much energy will be received on ground when the mirror is overhead at sunset?

    (Solar constant is the amount of Solar Radiation that falls on 1m^2 area per second above the atmosphere at a vertical angle. Assume that nothing is absorbed by the atmosphere.)

    Will the enrgy be equal to solar constant???? I dont think so. If you agree just tell me how to solve this.

    They probably want you to consider the angle of the reflector to the sun and earth. Draw a picture!

    I have drawn the picture but how will I find the angle etc. ? How will the angle help in getting the answer. It should be veritcal.
