How to Convert Terahertz to Micrometers

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 21 THz to µm:
  1. Convert to hertz: 21 THz = 21 × 1.0e+12 = 2.1e+13 Hz
  2. Apply formula: λ = 299,792,458 / 2.1e+13 Hz = 1.42758e-5 meters
  3. Convert to micrometers: 1.42758e-5 m / 1.0e-6 = 6295.64 µm

Reverse Conversion

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

  • 6295.64 µm → f = 299,792,458 / 1.42758e-5 m = 2.1e+13 Hz → 21 THz
