by Wien's Lâw. Apeak x T = constant %3D Just as the blackbody spectra of hot and cool light bulbs differ, the blackbody spectra of hot and cool stars differ as well. Consider two stars, Star A and Star B, identical except for their temperatures. The spectra of these stars are plotted below. Star A Star B 300 500 700 900 1100 Intensity

Transcribed Image Text:The relation that hotter objects emit light with a shorter peak wavelength is formally described
by Wien's Law.
Apeak × T = constant
Just as the blackbody spectra of hot and cool light bulbs differ, the blackbody spectra of hot
and cool stars differ as well. Consider two stars, Star A and Star B, identical except for their
temperatures. The spectra of these stars are plotted below.

Use Wien's law to calculate the answer to the following statement without looking up the
constant, showing your work: (Hint: Use a ratio to find TA/TB)
The hotter star is .
times hotter than the cooler star.
