Chemistry

3) The emission spetrum from stars can be used to determinetheir temperature ( they are blackbody emitters). our sun has atemperature of 5800 k.

a) use the wavelenght maximum equation to determine thewavelenght maximum for the sun ( in nanometers).

b) The star Bellatrix (in the orion constellation)has atemperature of 27,000k.

What is the wavelenght corresponding to the maximum intensity ofthe 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
