> Dear Sir,
> Do you know what the power of the surface of the sun is in watts/m^2? I

> where R is the distance of the Earth to the Sun for increase in intensity.
> The result seemed very high of 3 x 10^25 W/m^2. With a average photon energy

> thought it should be about 10^-14 meters. Thank you for your help.
