How to Convert Nanometers 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 400100 nm to THz:
  1. Convert to meters: 400100 nm = 400100 × 1.0e-9 = 0.0004001 m
  2. Apply formula: f = 299,792,458 / 0.0004001 m = 7.49294e+11 Hz
  3. Convert to terahertz: 7.49294e+11 Hz / 1.0e+12 = 1.19947e+11 THz

Reverse Conversion

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

  • 1.19947e+11 THz → λ = 299,792,458 / 7.49294e+11 Hz = 0.0004001 m → 400100 nm
