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 21210 nm to THz:
  1. Convert to meters: 21210 nm = 21210 × 1.0e-9 = 2.121e-5 m
  2. Apply formula: f = 299,792,458 / 2.121e-5 m = 1.41345e+13 Hz
  3. Convert to terahertz: 1.41345e+13 Hz / 1.0e+12 = 6.3586e+9 THz

Reverse Conversion

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

  • 6.3586e+9 THz → λ = 299,792,458 / 1.41345e+13 Hz = 2.121e-5 m → 21210 nm
