How to Convert Micrometers to Terahertz

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

Conversion Steps

  • The formula is: Frequency = Speed of Light / Wavelength
  • For example, to convert 70 µm to THz:
  1. Convert to meters: 70 µm = 70 × 1.0e-6 = 7.0e-5 m
  2. Apply formula: f = 299,792,458 / 7.0e-5 m = 4.28275e+12 Hz
  3. Convert to terahertz: 4.28275e+12 Hz / 1.0e+12 = 20985.5 THz

Reverse Conversion

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

  • 20985.5 THz → λ = 299,792,458 / 4.28275e+12 Hz = 7.0e-5 m → 70 µm
