### Wien's law $$\lambda max$$

Posted: Tue Oct 10, 2017 9:19 pm
Hello everyone,

I know lambda is what is used to represent wavelength however in Wien's law it represents intensity. To my knowledge these are completely different things, so is lambda used to represent both, or is intensity and wavelength related?

In Wien's law, lambda is still used to represent wavelength. Lambda max refers to the wavelength in the absorption spectrum where the absorbance is maximum. In other words, lambda max is the wavelength that corresponds to the maximum in the intensity which is where you might have gotten confused. Hope that helps!
