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 3121000 nm to THz:
- Convert to meters: 3.121e+6 nm = 3.121e+6 × 1.0e-9 = 0.003121 m
- Apply formula: f = 299,792,458 / 0.003121 m = 9.60565e+10 Hz
- Convert to terahertz: 9.60565e+10 Hz / 1.0e+12 = 9.35652e+11 THz
Reverse Conversion
To convert terahertz back to nanometers, use λ = c / f:
- 9.35652e+11 THz → λ = 299,792,458 / 9.60565e+10 Hz = 0.003121 m → 3.121e+6 nm
