femtosekunteihin
Femtosekunteihin refers to femtoseconds, which are units of time equal to one quadrillionth of a second. A femtosecond is represented as 10^-15 seconds. This incredibly short duration is difficult to comprehend in everyday terms. To put it into perspective, if one second were stretched out to the age of the universe (approximately 13.8 billion years), a femtosecond would be roughly one second. Light travels only about 300 nanometers in a femtosecond, which is a distance smaller than the wavelength of visible light.
Femtoseconds are crucial in various scientific fields, particularly in physics and chemistry, where they are used
