Question: the plexiglass plate of a solar greenhouse has a transmissivity...

Question details
  1. 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, calculate:
    1. the percent of incident solar radiation transmitted through the glass, and
    2. the percent of thermal radiation emitted by the interior objects that is transmitted out
