Frequently Asked Questions
-
What is wavelength measured in micrometres used for?
-
Wavelength in micrometres is commonly used in optical and infrared spectroscopy, fiber-optic telecommunications, laser engineering, remote sensing, and thermal imaging.
-
Why convert wavelength from micrometres to petametres?
-
Converting to petametres helps translate laboratory or terrestrial scale electromagnetic measurements to very large spatial scales relevant to astrophysics and cosmology.
