### Wien's Law

When are we supposed to use Wien's law? Is it going to be any problem with temperature associated with max wavelength or is it finding the temperature of particular things?

### Re: Wien's Law

You use Wien's law when you need to find temperature given a maximum wavelength of radiation or when you need to find a maximum wavelength when given the temperature. If they mention max wavelength of anything and want you to find the temperature that's when you use Wien's law, and I don't think you'd use it to find temperature if they didn't mention specifically the maximum wavelength.

I believe Wien's law is used to determine either the temperature or wavelength based on which variables are provided in the problem. However, I don't think we would need to know Wien's law as of now because on Outline 2 Dr. Lavelle did not put 1B.11 as an option which was the question about Wien's Law.
