How to calculate bandwidth with freqency?

Equation: f * λ = c

where:

f = frequency in Hertz (Hz = ^{1}/_{sec})

λ = wavelength in meters (m)

c = the speed of light (approximately equal to 3*10^{8} ^{m}/_{s})

Bandwidth = c\λ

nm = 10-9 m

subtract the difference between the bandwidth for the two values

Frequency (nm) | Speed of Light | Bandwidth (GHz) |

850 | 300000000 | 352941.1765 |

851 | 300000000 | 352526.4395 |

Bandwidth Between: | 414.7369876 | |

Approx: | 415 GHz | |

Frequency (nm) | Speed of Light | Bandwidth |

1310 | 300000000 | 229007.6336 |

1311 | 300000000 | 228832.9519 |

Bandwidth Between: | 174.6816427 | |

Approx: | 175 GHz | |

Frequency (nm) | Speed of Light | Bandwidth |

1550 | 300000000 | 193548.3871 |

1551 | 300000000 | 193423.5977 |

Bandwidth Between: | 124.7894179 | |

Approx: | 125 GHz |
