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 8221 nm to THz:
- Convert to meters: 8221 nm = 8221 × 1.0e-9 = 8.221e-6 m
- Apply formula: f = 299,792,458 / 8.221e-6 m = 3.64667e+13 Hz
- Convert to terahertz: 3.64667e+13 Hz / 1.0e+12 = 2.46459e+9 THz
Reverse Conversion
To convert terahertz back to nanometers, use λ = c / f:
- 2.46459e+9 THz → λ = 299,792,458 / 3.64667e+13 Hz = 8.221e-6 m → 8221 nm
