How do you find the peak wavelength?

To calculate a peak wavelength, divide Wien's displacement constant by the absolute temperature.

What is the peak wavelength?

Peak Wavelength - Peak wavelength is defined as the single wavelength where the radiometric emission spectrum of the light source reaches its maximum. More simply, it does not represent any perceived emission of the light source by the human eye, but rather by photo-detectors.

What does the peak wavelength tell us?

From the wavelength at the peak, the temperature can be deduced from the Wien displacement law. The change in the visual color of stars of different temperatures can be traced out on a chromaticity diagram.
