Frequently Asked Questions
-
What is nanohertz used for?
-
Nanohertz measures very low frequencies used to study phenomena with multi-year to multi-decade cycles such as gravitational waves and long-term astronomical patterns.
-
What kinds of phenomena correspond to exahertz frequencies?
-
Exahertz frequencies relate to electromagnetic radiation in the soft X-ray range and are relevant in fields like X-ray spectroscopy and astrophysical high-frequency emissions.
-
Why is converting between nanohertz and exahertz important?
-
Converting these units helps connect frequency scales from extremely slow geophysical or astrophysical events to very fast electromagnetic phenomena, aiding cross-disciplinary understanding.
