How to Convert Terahertz to Nanometers

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

Conversion Steps

  • The formula is: Wavelength = Speed of Light / Frequency
  • For example, to convert 9000 THz to nm:
  1. Convert to hertz: 9000 THz = 9000 × 1.0e+12 = 9.0e+15 Hz
  2. Apply formula: λ = 299,792,458 / 9.0e+15 Hz = 3.33103e-8 meters
  3. Convert to nanometers: 3.33103e-8 m / 1.0e-9 = 2.69813e+9 nm

Reverse Conversion

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

  • 2.69813e+9 nm → f = 299,792,458 / 3.33103e-8 m = 9.0e+15 Hz → 9000 THz
