Wien's displacement law
Lamdamax*temp=b
where λmax is the peak wavelength, T is the absolute temperature of the black body, and b is a constant of proportionality called Wien's displacement constant, equal to 2.8977721(26)×10−3 m K.[1]
Watch your units.
2. It changes according to the inverse square law.
1.10=(orbital radius/changed distance)^2
or orbital distance changes =sqrt1.1
= about 1.05 or five percent
1. What solar temp is needed for the peak intensity of radiation to occue at .2 micrometers? Remembering that humans can see light only between .4 and .7 microns, would the sun look brighter or dimmer at this new temp?
2. How much variation in earth orbital distance from the sun is needed to alter the solar constant by 10%?
THANKS!!

dentify the fruit or vegetable you selected and relate the second law of thermodynamics to the changes in energy observed in Appendix CHow did the amount of energy gained compare to the amount of energy lost as heat at the second through fourth trophic levels? Considering the amount of energy required to produce animal-based foods and goods, should humans change their habits so they consume products closer to the bottom of the food chain because it is more efficient?
