Common Use Cases
-
Relating visible‑light and laser emission wavelengths to cosmological wave scales.
-
Describing extremely low-frequency gravitational waves with interstellar distances.
-
Specifying large-scale plasma or density waves in the heliosphere and interstellar medium.
-

Tips & Best Practices
-
Ensure input values represent wavelength in vacuum conditions for accurate conversion.
-
Use the tool to bridge scales between optical measurements and astrophysical distances.
-
Be mindful that values converted to petametres will be extremely small due to scale differences.
-
Consider the context of your application to decide when this conversion is relevant.
Limitations
-
Converted values are extremely small when converting typical nanometre wavelengths to petametres.
-
Conversion assumes vacuum; it does not factor in refractive index variations in different media.
-
Practical measurement limits may affect the usefulness of extremely small converted values.
Frequently Asked Questions
-
What is the relationship between wavelength and frequency in this conversion?
-
Wavelength and frequency relate through the speed of light, where frequency equals the speed of light divided by wavelength (f = c/λ) in vacuum.
-
Why convert wavelength from nanometres to petametres?
-
This conversion helps relate short wavelengths used in optics to the extremely long wavelengths relevant in astrophysical and cosmological phenomena.
-
Are medium effects like refraction considered in this conversion?
-
No, this conversion assumes vacuum conditions and does not account for refractive effects caused by different media.
Key Terminology
-
Wavelength in nanometres [nm]
-
Distance between successive peaks of an electromagnetic wave measured in nanometres, commonly used for optical and near-infrared radiation.
-
Wavelength in petametres [Pm]
-
Distance between successive crests of a wave expressed in petametres, used for extremely long wavelengths relevant in astrophysical and cosmological contexts.
-
Conversion formula
-
The formula stating 1 wavelength in nanometres equals 1e-24 wavelengths in petametres.
