Wien's Law states the relationship between the wavelength at which a blackbody curve peaks and the temperature of the blackbody. Temperature in Kelvins 2.9x106 Imax (in nm) (Ipt) Question 4: Using your result in Q2, calculate the temperature in Kelvins of the blackbody whose spectrum you have drawn. Temperature Show your work here for your calculation (Ipt) Question 5: Suppose you measure the spectrum of a blackbody with a temperature much much hotter than what you found in Question. Do you expect its peak to be at bigger or smaller wavelengths than for the spectrum above? Explain your answer Question 6: What kind of spectrum is shown to the right? LO 400 420 440 460 480 600 620 340 60 580 600 640 640 60 60 700 Question 7: What kind of spectrum is shown to below?
