Wiens Displacement Law

Wiens Displacement Law states that the wavelength at which the emission of a black body is at its maximum is inversely proportional to its temperature. The law is expressed as:

T = λmax / b

where T is the temperature in Kelvin, λmax is the wavelength at maximum emission in meters, and b is the Wiens Displacement Constant, approximately 2.898 × 10-3 m·K.

Applications

This calculator is useful in astrophysics for determining the temperature of stars based on their emitted radiation. It is also used in thermodynamics and material science to study black body radiation.
