3) The emission spetrum from stars can be used to determine their temperature ( they are blackbody emitters). our sun has a temperature of 5800 k.
a) use the wavelenght maximum equation to determine the wavelenght maximum for the sun ( in nanometers).
b) The star Bellatrix (in the orion constellation)has a temperature of 27,000k.
What is the wavelenght corresponding to the maximum intensity of the emisson from Bellatrix?
Wavelength of max emission (um) = 2897 umK / Temperature
a) Wavelength of max emission (um) = 2897umK / 5800
= 0.4995 um
b) Wavelength of max emission (um) = 2897umK / 27000
= 0.1073 um
