- The plexiglass plate of a solar greenhouse has a transmissivity
of 0.85 for wavelengths between 0.35 and 2.8 µm and is completely
opaque at shorter and longer wavelengths. If the sun is a blackbody
radiating energy to the earth’s surface at an effective temperature
of 5770 K and the interior of the greenhouse is at 303 K,
- the percent of incident solar radiation transmitted through the glass, and
- the percent of thermal radiation emitted by the interior objects that is transmitted out
