1 E-18 s
From Wikipedia, the free encyclopedia
10-18 seconds is a very short period of time. This period of time is called an attosecond.[1] It can also be written as "1 as" or 0.000000000000000001 seconds, or described as one quintillionth of a second. Because it can be hard to think about how short this period of time is, on this page is a list of descriptions of periods of time longer than 1 attosecond, but shorter than one femtosecond (which is 10-15 seconds). This should help when thinking about periods of time that have different orders of magnitude.

- 1 attosecond: It takes 1 attosecond for light to travel the length of three hydrogen atoms.
- 1 attosecond: It takes 1 attosecond for an atomic nucleus to react when another particle hits it.
- 150 attoseconds: It takes 150 attoseconds for an electron to circle the nucleus of an atom.
- 320 attoseconds: It takes about 300 attoseconds for an electron to jump from one atom to another.
