Smaller than a femtosecond (10^-15 seconds) are time intervals measured in attoseconds (10^-18 seconds) and zeptoseconds (10^-21 seconds). These units are often used in fields like ultrafast physics to study rapid processes such as electron movements in atoms and molecular interactions. While femtoseconds are commonly associated with light wave cycles, attoseconds allow scientists to observe phenomena at even shorter timescales.
