I zoomin on the spectra for 41 cygnus to and used the pointer to read the point at the peak. The reading was 4020.5435 A and 6.891e-14 ergs.... Using Wein's equation, the temperature was calculated to be 7190 k.
From the graphical analysis 3, my peak wavelength is 4020.54 angstrom (6.891E-14 ergs). Using Wien's Displacement Law : T = 2.897 E+7 / lambda max, the temperature is 7205 K. My estimated value for the temperature of 41 cygnus star is 7200K
Using the examine tool of Graphical Analysis, the highest peak wavelength is 4020.54 angstrom. Using the online calculator for Wien's law, my temperature for this star is 7207K. Using 2Sigfig I got 7200K for 41_cyg
Using the examine tool of graphical analysis, I estimated that the peak should correlate to the highest peak on the graph which was at 4020.54 angstrom. Using Wien's equation, I calculated the temperature of 41 Cygnus to be 7200 K rounding to 2 sig. figs.
I got 4020A for the peak wavelength. Using the conversion factor of 1.0x10^10 meters/A, the peak wavelength is 4.02x10^-7 meters, or in the violet part of the visible spectrum. The temperature in Kelvin is (2.89x10^-3 Km)/(4.02x10^-7m) = 7190 K.
I measured peak wavelength as 4020.5 nm and
ReplyDeleteby using Wien`s law, I calculated temperature of 41 Cygnus as 7189K.
Wein’s Law:
ReplyDeleteλmax = (2.89 × 10-3 K m)/T
Derived for temperature:
T = (2.89 × 10-3 K m)/ λmax
Wavelength from Graphical Analysis = 4020 Angstroms or 4000 when considering significant figures
Conversion
4000 Angstroms = 400 nm = 4.00 x 10-7 m
Calcualtion:
T= (2.89 × 10-3 K m)/ 4.00 x 10-7 m
T= 7225 K

ReplyDeleteI got the same peak wavelength (4021 angstrom) using Graphical Analysis. Plugging in this value to Wien's law formula, my temperature is 7192K.
ReplyDeleteIn the simulator (in module 2), I got a temperature of 7210K. Using 2 sigfig, I have 7200K for 41_cyg
My peak wavelength of the spectrum is 4020.54 angstrom. Applying Wien's law, the computed temperature is around 7200K (using 2SF)

ReplyDeleteFor 41_Cyg I estimated the peak to be about
ReplyDelete4020 Angstroms . Using Wien’s law
T (max K) = 2.90x10^-3 m•K/4.02x10^-7 m
T = 7200 K
From GA, the peak is 4020.5 angstrom and using Wien's law, I got a temperature of 7200K (expressed in 2 SF)
