**Calculation Parameters:** Medium of propagation is assumed as vacuum

The energy of photon as a function of frequency (E(f)) is J [Joule] |

The energy of photon as a function of wavelength (E(λ)) is J [Joule] |

Energy of photon as a function of frequency (E(f)) calculation |
---|

E(f) = h ∙ f E(f) = ∙ E(f) = |

Energy of photon as a function of wavelength (E(λ)) calculation |

E(λ) = h ∙ c/λE(λ) = ∙ /E(λ) = /λE(λ) = |

Energy Of Photons Calculator Input Values |
