Key Features

Converts petahertz frequencies to wavelengths in exametres using the formula λ = c / f.
Supports frequencies typical in ultrafast optics and high-frequency spectroscopy.
Provides conversion relevant to large-scale cosmological and astrophysical measurements.

Examples

1 PHz equals 2.99792458 × 10⁻²⁵ exametres.
5 PHz converts to 1.49896229 × 10⁻²⁴ exametres.

Common Use Cases

Mapping ultrafast laser frequencies to spatial wavelengths in photonics and spectroscopy.
Relating electromagnetic wave frequencies to cosmological-scale distances.
Studying large astronomical structures where metre-based units are impractical.

Tips & Best Practices

Understand that petahertz frequencies translate to extremely small wavelengths in exametres.
Use this conversion primarily for theoretical or astrophysical contexts rather than everyday measurements.
Remember that the wavelength calculation uses the speed of light divided by frequency.

Limitations

Wavelengths resulting from petahertz frequencies are extraordinarily small in exametre terms.
Exametre-scale wavelengths usually correspond to ultra–low frequency waves, not typical petahertz ranges.
Practical use of exametre wavelengths mostly applies to cosmology and astrophysics, not ultrafast optics.
