Frequently Asked Questions
-
What is a second and how is it defined?
-
A second is the SI base unit of time, defined by the duration corresponding to 9,192,631,770 periods of radiation from the cesium-133 atom, serving as a standard for precise timing.
-
What is a femtosecond used to measure?
-
A femtosecond, which is one quadrillionth of a second, measures extremely short time intervals such as ultrafast laser pulses and rapid molecular or electronic processes.
-
Why convert seconds to femtoseconds?
-
Converting seconds to femtoseconds helps scientists and engineers analyze phenomena happening on very short timescales, important in fields like femtochemistry and ultrafast laser physics.
Key Terminology
-
Second [s]
-
The SI base unit of time, defined by the radiation period of cesium-133, used widely in precise scientific and engineering timing.
-
Femtosecond [fs]
-
A unit of time equal to 10^-15 seconds, representing extremely brief intervals used in ultrafast phenomena studies.
