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 402 THz to nm:
  1. Convert to hertz: 402 THz = 402 × 1.0e+12 = 4.02e+14 Hz
  2. Apply formula: λ = 299,792,458 / 4.02e+14 Hz = 7.45752e-7 meters
  3. Convert to nanometers: 7.45752e-7 m / 1.0e-9 = 1.20517e+8 nm

Reverse Conversion

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

  • 1.20517e+8 nm → f = 299,792,458 / 7.45752e-7 m = 4.02e+14 Hz → 402 THz
