Earth's atmospheric magnetic flux density is 7.0 mT near the north pole. Near the equator, a power density of 4 kW/m^2 exists from sunlight. A) Determine values for electric and magnetic field strengths due to solar electromagnetic radiation and magnetic flux density of solar EM radiation. B) Compare magnetic flux density of Earth and solar radiation.

Calculate the expected solar radiative flux at our latitude (40°N) at solar noon (time of peak radiation) at three times of year: equinox, and both summer and winter solstice. (Please ignore the role of the atmosphere here – in other words calculate your answer as if there were no atmosphere altering the incoming radiation.)

A solar collector is irradiated by solar flux and a diffuse atmospheric flux. The solar flux is 1000 W/m2, and the angle of incidence is 45°. The effective blackbody sky temperature is 244 K, and the blackbody solar temperature is 5785 K. The collector is a nongray, isothermal diffuse surface with spectral hemispherical emissivity as shown. What is the net radiant flux absorbed by the collector? = 45° T.= 244 K 1000 W/m2 0.9 0.1 T 320 K 2.2 um...

In a stellar atmosphere, the radiation intensity passing through various layers is given as Iout = (Iin)e(−τ) . a) How large must the optical depth through a material be for the material to absorb 50% of the incident photons, as in the solar photosphere? b) Regions in the solar chromosphere have an optical depth of τ = 0.1. What fraction of the Sun’s radiation intensity is transmitted through this region? c) In the optically thin limit, Iout = Iin*e−τ reduces...
