Wein's Law: Example 1B.1

[506002081]

Hello,

So in the textbook, it is said that Wein's law can be written as T (temperature)= constant/ lambda max . But when I went on to do the example problem 1B.1, the solve section immediately places 2.9mm K (2.9 x 10^-3m K) as the constant in Wein's law. Why is this? Where did that information come from? Can we use this as the constant for all future Wein's law problems? Thank you!

Wien's constant will always be equal to 2.9mm K just like how the speed of light constant c is always equal to approx 3x10^8. You should always use 2.9mm K when trying to relate the thermodynamic temperature of a black body with the maximum wavelength.
