What is Wien's Displacement Law?

Wien's displacement law states that the wavelength at which the emission of a blackbody is at its maximum intensity is inversely proportional to its temperature. This relationship is crucial in physics and astronomy for determining the temperature of stars and other celestial objects.

How to Use This Calculator

  1. Enter the temperature in Kelvin (K). The calculator defaults to 3000K, which is approximately the surface temperature of the Sun.
  2. Select whether to use the default Wien's displacement constant or a custom value.
  3. Click the "Calculate" button to compute the peak wavelength.
  4. The result will be displayed in nanometers (nm).

Practical Applications

This calculator can be used to:

  • Estimate the color temperature of stars
  • Determine the spectral characteristics of blackbody radiation
  • Understand thermal radiation principles in physics

Note: This calculator assumes ideal blackbody radiation. Real objects may deviate from this behavior.
