Technical Information

Wien's Displacement Law

The peak wavelength of blackbody radiation is inversely proportional to temperature: λmax = b/T, where b ≈ 2.898 × 10⁻³ m·K is Wien's constant.

Key Relationships:

  • • λmax × T = 2.898 × 10⁻³ m·K
  • • νmax ≈ 5.88 × 10¹⁰ Hz/K × T
  • • E = hν = hc/λ (photon energy)
  • • Higher temperature = shorter wavelength

Physical Applications

Blackbody radiation calculations are fundamental to understanding thermal emission and energy distribution in various physical systems.

Common Examples:

  • • Sun: 5778 K → 502 nm (green-yellow)
  • • Human body: 310 K → 9.35 μm (infrared)
  • • Room temperature: 293 K → 9.89 μm (infrared)
  • • Red hot: 1000 K → 2.9 μm (infrared)
  • • White hot: 2000 K → 1.4 μm (infrared)
