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 20000 THz to nm:
  1. Convert to hertz: 20000 THz = 20000 × 1.0e+12 = 2.0e+16 Hz
  2. Apply formula: λ = 299,792,458 / 2.0e+16 Hz = 1.49896e-8 meters
  3. Convert to nanometers: 1.49896e-8 m / 1.0e-9 = 5.99585e+9 nm

Reverse Conversion

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

  • 5.99585e+9 nm → f = 299,792,458 / 1.49896e-8 m = 2.0e+16 Hz → 20000 THz
