如何计算Black Body Peak
learn.whatIsHeading
Black body peak wavelength (Wien's law) shows where maximum thermal radiation occurs: λ_peak = 2.898×10⁻³ / T.
分步指南
- 1Input object temperature (Kelvin)
- 2Calculate peak wavelength
- 3Determine radiation type: infrared, visible, ultraviolet
例题解析
输入
T = 5778 K (Sun)
结果
λ ≈ 501 nm (green, why Sun looks white)
Eyes sensitive to whole spectrum
常见错误注意事项
- ✕Confusing peak with average wavelength
- ✕Forgetting Kelvin temperature required
常见问题
Why does hotter mean shorter wavelength?
Higher vibration frequency, shorter wavelength for same photons.
