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 221000 THz to nm:
  1. Convert to hertz: 221000 THz = 221000 × 1.0e+12 = 2.21e+17 Hz
  2. Apply formula: λ = 299,792,458 / 2.21e+17 Hz = 1.35653e-9 meters
  3. Convert to nanometers: 1.35653e-9 m / 1.0e-9 = 6.62541e+10 nm

Reverse Conversion

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

  • 6.62541e+10 nm → f = 299,792,458 / 1.35653e-9 m = 2.21e+17 Hz → 221000 THz
