Quiz
Question #1
How long does one femtosecond last?
One femtosecond lasts 1x10^-15 seconds (Equivalent to one millionth of a billionth of a second.)
The Answer
Question #2
What is the purpose of studying femtochemitry?
Scientists study femtochemsitry to study the actions of atoms within a molecule, causing them to re-arrange and form new molecules.
The Answer
Question #3
What are practical applications of femtochemistry?
Applications of femtochemistry are for improving catlysts for uses in the field of medicine or for molecular electronics, which can be used to create smaller electoic devices with the same capabilites of a larger device.
