Astronomy Wein’s Formula

Question

1. Using the graph that you constructed and from the graph estimated λmax (the best you can) for the following cases:

λmax (5000 K) =                    

λmax (5500 K) =                      

λmax (6000 K) =                      

Answer 1

Wien's law gives λ_max = (2.898 x 10^-3 m∗K)/T. Don't know what graph you have, but we can calculate:

λ_max (5000 K) = 5.80 x 10^-7 m = 580 nm.

λ_max (5500 K) = 5.27 x 10^-7 m = 527 nm.

λ_max (6000 K) = 4.83 x 10^-7 m = 483 nm.
