Question

The emission spectrum from stars can be used to determine thier temperature (they are blackbody emitters). our sun has a temperature of 5800k.

a) use the wavelenght maximum equation to determine the wavelenght maximum for the sun in (nm)

b) The star Bellatrix ( in Orion constellation) has a temperature of 27,000k. what is the wavelenght corresponding to the maximum intensity of emission coming from bellatrix?

c) in question above determine the orthogonality by determine if the functions are even or odd. show work (graphs).

Explanation / Answer

a) wavelength maximum = b/T

                    = (2.9×10^(6))/ 5800

                    = 500 nm

  
b) wavelength maximum = b/T

           = (2.9×10^(6))/ 27000

           = 107.4074 nm
