Wien's displacement law states at which wavelength or frequency
the emission of thermal radiation from a black body peaks, dependent on its temperature.
Due to the non-linear conversion between wavelength and frequency intervals
there are different results in a plot with linear wavelength or linear frequency, respectively.
The calculation of the wavelength of the peak photon rate also leads to different results.
Type the temperature (in °C or in K), a wavelength (in nm), or a frequency (in MHz)
into the corresponding field.
After a click on any empty space in the window or on the "calculate" button,
the result is shown.
For a linear plot of wavelength a wavelength is calculated
and for a linear plot of frequency a frequency, respectively.
In the last column these wavelengths are converted to frequency and vice versa.
This allows a direct comparison of the different plots.
The grey fields of the last column do not allow input.
Move the mouse over a unit or click on it to read its full name.

The sun has its peak emission at a wavelength of about 500 nm.
What is the temperature of this black body following Wien's displacement law?
Type "500" into the field of the wavelength (peak emission, linear wavelength).
After a mouse click on any free space of the window or on the "calculate" button,
you can read the result (5975.5 K).
