How to Convert Terahertz to Nanometers

Wavelength and frequency are inversely related through the speed of light. The formula is: λ = c / f, where λ is the wavelength, c = 299,792,458 m/s (speed of light in vacuum), and f is the frequency.

Conversion Steps

  • The formula is: Wavelength = Speed of Light / Frequency
  • For example, to convert 400200 THz to nm:
  1. Convert to hertz: 400200 THz = 400200 × 1.0e+12 = 4.002e+17 Hz
  2. Apply formula: λ = 299,792,458 / 4.002e+17 Hz = 7.49107e-10 meters
  3. Convert to nanometers: 7.49107e-10 m / 1.0e-9 = 1.19977e+11 nm

Reverse Conversion

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

  • 1.19977e+11 nm → f = 299,792,458 / 7.49107e-10 m = 4.002e+17 Hz → 400200 THz
