Tips & Best Practices
-
Ensure the wave propagation speed used matches the medium, commonly the speed of light in vacuum.
-
Use this conversion to connect large wavelength phenomena with their high-frequency equivalents.
-
Apply the tool within its suitable domain; very long wavelengths map to very low terahertz frequencies.
-
Cross-verify conversions when applying to specific scientific or engineering contexts.
Limitations
-
The conversion assumes wave speed is known and often the speed of light in vacuum, which can affect accuracy if different.
-
Wavelengths measured in kilometres correspond to frequencies far below the terahertz range, limiting practical use at THz scale for such large values.
-
Direct measurement of frequencies at terahertz scale is uncommon for very large wavelength values.
