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 201 nm to THz:
  1. Convert to meters: 201 nm = 201 × 1.0e-9 = 2.01e-7 m
  2. Apply formula: f = 299,792,458 / 2.01e-7 m = 1.4915e+15 Hz
  3. Convert to terahertz: 1.4915e+15 Hz / 1.0e+12 = 6.02583e+7 THz

Reverse Conversion

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

  • 6.02583e+7 THz → λ = 299,792,458 / 1.4915e+15 Hz = 2.01e-7 m → 201 nm
