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 91 nm to THz:
  1. Convert to meters: 91 nm = 91 × 1.0e-9 = 9.1e-8 m
  2. Apply formula: f = 299,792,458 / 9.1e-8 m = 3.29442e+15 Hz
  3. Convert to terahertz: 3.29442e+15 Hz / 1.0e+12 = 2.72811e+7 THz

Reverse Conversion

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

  • 2.72811e+7 THz → λ = 299,792,458 / 3.29442e+15 Hz = 9.1e-8 m → 91 nm
