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 4.2012 × 107 nm to THz:
  1. Convert to meters: 4.2012e+7 nm = 4.2012e+7 × 1.0e-9 = 0.042012 m
  2. Apply formula: f = 299,792,458 / 0.042012 m = 7.13588e+9 Hz
  3. Convert to terahertz: 7.13588e+9 Hz / 1.0e+12 = 1.25949e+13 THz

Reverse Conversion

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

  • 1.25949e+13 THz → λ = 299,792,458 / 7.13588e+9 Hz = 0.042012 m → 4.2012e+7 nm
