(a) What
6.133 Blackbody radiation is the term used to describe thedependence of the radiation energy emitted by an objecton wavelength at a certain temperature. Planck proposed the quantum theory to account for the dependence.Shown in the figure is a plot of the radiation energyemitted by our sun versus wavelength. This curve ischaracteristic of objects at about 6000 K, which is thetemperature at the surface of the sun. At a highertemperature, the curve has a similar shape but themaximum will shift to a shorter wavelength. (a) Whatdoes this curve reveal about two consequences ofgreat biological significance on Earth? (b) How areastronomers able to determine the temperature at thesurface of stars in general?
