Black body peak wavelength (Wien's law) shows where maximum thermal radiation occurs: λ_peak = 2.898×10⁻³ / T.
ステップバイステップガイド
- 1Input object temperature (Kelvin)
- 2Calculate peak wavelength
- 3Determine radiation type: infrared, visible, ultraviolet
解いた例
入力
T = 5778 K (Sun)
結果
λ ≈ 501 nm (green, why Sun looks white)
Eyes sensitive to whole spectrum
避けるべきよくある間違い
- ✕Confusing peak with average wavelength
- ✕Forgetting Kelvin temperature required
よくある質問
Why does hotter mean shorter wavelength?
Higher vibration frequency, shorter wavelength for same photons.
