How to Convert Nanometers to Terahertz

Frequency and wavelength are inversely related through the speed of light. The formula is: f = c / λ, where f is the frequency, c = 299,792,458 m/s (speed of light in vacuum), and λ is the wavelength.

Conversion Steps

  • The formula is: Frequency = Speed of Light / Wavelength
  • For example, to convert 9000 nm to THz:
  1. Convert to meters: 9000 nm = 9000 × 1.0e-9 = 9.0e-6 m
  2. Apply formula: f = 299,792,458 / 9.0e-6 m = 3.33103e+13 Hz
  3. Convert to terahertz: 3.33103e+13 Hz / 1.0e+12 = 2.69813e+9 THz

Reverse Conversion

To convert terahertz back to nanometers, use λ = c / f:

  • 2.69813e+9 THz → λ = 299,792,458 / 3.33103e+13 Hz = 9.0e-6 m → 9000 nm
