Frequently Asked Questions
-
What does wavelength in exametres measure?
-
It measures the spatial period of a wave in exametres, where one exametre equals 10^18 metres, used mainly for extremely long wavelengths in astrophysics and cosmology.
-
What is a petahertz used for?
-
Petahertz is a frequency unit equal to 10^15 hertz, commonly used to describe extremely fast oscillations such as those found in ultrafast optics and high-frequency spectroscopy.
-
Why convert between exametres and petahertz?
-
Converting helps translate ultra-long spatial wavelengths to extremely high-frequency rates, useful in bridging scales from large cosmological structures to electromagnetic wave properties.
