Question

For car under the sun,
the windshield has 0.92 transmissivity (symbolized in T) for wavelength

between 3 x 10^(-6)m and 3 x 10^(-5)m.

opaque to other wavelength

car considered as blackbody at 300K

sun considered as balckbody at 5800K, producing irradiation of 1100w/m2 on the windshield

Calculate

1. total T of windshield from sun's irradiation.

2. total T of windshield from interior of car

3. rate of sun's E transmitted thr. windshield

4. rate the radiant E from the inte. of car transmitted thr. windshield

5. calculate max for 300K blackbody

6. the % of all emitted E that lies in the visible wl range for a 300K blackbody
