Wien's displacement law

temperature:
T = K °C
peak emission (linear wavelength):
λ = nm ν = MHz
peak emission (linear frequency):
ν = MHz λ = nm
peak photon rate (linear wavelength):
λ = nm ν = MHz
peak photon rate (linear frequency):
ν = MHz λ = nm


rounding: significant digits.
Decimal sign:

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.

Usage: 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. Use the "reset" button to reset your calculation.

Example: Sonne 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).

Remarks:
- Please note the remarks about the representation of numbers..
- There is no warranty for the calculation. Cactus2000 is not responsible for damage of any kind caused by wrong results.
