Wein's Formula p. 6 1. The brightest color produced by an object at temperature of 6000 K is at a wavelength of 483 nm. What is the wavelength of the brightest color produced by a 3000 K object? (do the math below) 1max X T1=22max x T2 2. The brightest color emitted by a certain star has a wavelength of 240 nm. Given that a 6000 K star produces its peak radiation at a wavelength of 483 nm, what is the temperature of the star? (do the math below) 2max x T1 = 22max x T2 3. Using the Wien's formula calculate Amax for the following cases: Amax (0.2897/T) x 107 (nm) = Amax (5000 K)= Amax (5500 K)= max (6000 K) = 4. Using the graph that you constructed and from the graph estimated max (the best you can) for the following cases: Amax (5000 K)= Amax (5500 K)= Amax (6000 K)= 5. Why is there an absence of the color black and of the color white in the rainbow? 6.
