Units And Measurement

Frequency difference between stokes and antistokes lines are called Raman frequencies.

The second is the duration of periods of the radiation corresponding to the transition between the two hyperfine levels of the ground state of the cesium- atom.

- Electronic oscillators, atomic clocks, and decay of elementary particles are high-precision tools for measuring very small time intervals (in nanoseconds, microseconds, or even femtoseconds). - Spring oscillators, however, operate on mechanical time scales and are relatively slow. They cannot measure very small time intervals precisely. Thus, the spring oscillator is not suitable for measuring very short durations.

Relative error is calculated as: For the first length: For the second length:
