A greenhouse is constructed of silica glass that is known to transmit 92% of incident radiant energy between wavelengths of 0.35 and 2.7 mm. The glass may be considered opaque for wavelengths above and below these limits. 

Considering the sun to emit as a black body at 5800 K, determine the percent of solar radiation that will pass through the glass. 

If the plants on the inside of the greenhouse have an average temperature of 300 K, and emit as a black body, what fraction of their emitted energy will be transmitted through the glass?
