Harrison is, the time it takes for light to travel one fermi, which is approximately the size of a nucleon. Informally it has been defined as "one light-foot," which works out as approximately one nanosecond. Newer Post Older Post Home. Popular Posts. Fahrenheit is used only by 5 countries.
The speed of light in a vacuum provides a convenient universal relationship between distance and time, so in physics particularly in quantum physics and often in chemistry, a jiffy is defined as the time taken for light to travel some specified distance.
Since Lewis, other physicists and chemists have suggested alternative distances to measure a jiffy, rather than light traveling for a centimeter, but the original value is still most typically used in physics and chemistry.
Specifically, it was. However, today it usually just means. In computing, a jiffy was originally the time between two ticks of the system timer interrupt. It is not an absolute time interval unit, since its duration depends on the clock interrupt frequency of the particular hardware platform. In astrophysics and quantum physics a jiffy is, as defined by Edward R. Harrison, the time it takes for light to travel one Fermi, which is approximately the size of a nucleon. This would make the jiffy equal to 3.
In the 20th century Richard Tolman suggested that a jiffy should be the length of time it takes a photon light particle to travel from one side of a nucleon neutron or proton to the other.
In physics, a jiffy is the time taken for light to travel to a specified distance, or the time it takes for light to travel one fermi making a jiffy 3 x 10 to the th power seconds.
