1 E-20 s - Definition and Overview

To help compare orders of magnitude of different times this page lists times between 10^-20 seconds and 10^-19 seconds (10 zeptoseconds and 100 zeptoseconds) See also times of other orders of magnitude.

• shorter times
• about 17 zs – the approximate period of electromagnetic radiation at the boundary between gamma rays and X-rays.
• longer times
