Calculadora de Longitud de Onda Pico de WienFórmula

## Wien's Displacement Law

**lambda_max = b / T**

where b = 2.8978 × 10⁻³ m·K (Wien's displacement constant).

Hotter objects peak at shorter wavelengths. The Sun (5778 K) peaks at about 502 nm (green-yellow visible light). A human body (310 K) peaks at about 9.35 µm (infrared).

Ejemplo Resuelto

The Sun at T = 5778 K.

  1. lambda_max = 2.8978e-3 / 5778
  2. = 5.016e-7 m = 501.6 nm
  3. This is in the green part of the visible spectrum.
