The Emission Ability of a Black Body through Rayleigh-Jeans Relation Calculator will calculate the:

- Emission ability of a black body using the Rayleigh-Jeans relation

**Calculation Parameters:** The object is considered as a perfect (absolute) black body; the relation is valid only for long wavelengths

The emissivity of black body (e^{0} (λ)) is K/(s · m^{3}) [Kelvin per second times metre at power three] |

Emissivity of black body (e^{0} (λ)) calculation |
---|

e^{0} (λ) = 2π ∙ c ∙ T/ λ^{4}e ^{0} (λ) = (2 × ) ∙ ∙ / ^{4}e ^{0} (λ) = ∙ ∙ /e ^{0} (λ) = /e ^{0} (λ) = |

Rayleigh Jeans Relation Calculator Input Values |

Light speed (c) m/s [metre per second] |

Temperature of the black body (T) K [Kelvin degree] |

Wavelength of EM radiation (λ) m [metre] |

Archimedes' Constant (π) |

e^{0} (λ) = *2π ∙ c ∙ T**/** λ*^{4}
