Tips & Best Practices
-
Ensure wavelength units are correctly entered in nanometres for accurate conversion
-
Use the tool primarily for vacuum conditions since dispersion effects are not accounted for
-
Apply results mainly in high-frequency electromagnetic contexts such as X-ray and astrophysical research
-
Cross-check conversions when working at very small scales where advanced physical models may be necessary
-
Refer to examples to understand typical conversion outputs before applying to experimental data
Limitations
-
The conversion assumes electromagnetic waves propagate through vacuum without dispersion effects
-
Quantum and relativistic effects at scales below nanometres are not considered by this simple conversion
-
Typical visible and near-infrared wavelengths correspond to much lower frequencies than those expressed in exahertz
-
Direct practical overlap between wavelength and exahertz frequency ranges is limited for everyday measurements
Frequently Asked Questions

Key Terminology
-
Wavelength in nanometres [nm]
-
The distance between successive peaks of an electromagnetic wave measured in nanometres, often used to describe optical and near-infrared radiation.
-
Exahertz [EHz]
-
An SI unit of frequency equal to 10^18 hertz, representing extremely high frequency electromagnetic waves such as those in the soft X-ray region.
-
Frequency–wavelength relation
-
The inverse relationship where frequency is equal to the speed of light divided by wavelength, important in electromagnetic wave analysis.
