MCQ
Which of the technique$(s)$ is/ are not used for measuring time intervals?
- AElectrical oscillator.
- BAtomic clock.
- ✓Spring oscillator.
- DDecay of elementary particles.
✓
Answer
Correct option: C.
Spring oscillator.
Spring oscillator cannot be used to meausre time intervals. But in electrical oscillator electrical oscillations are produced in $L-C$ circuit and oscillators are maintained with the help of transistor. $1$ us can be measured with these oscillators.
Atomic clock are based on periodic vibrations taking place within the atoms.
Decay of elementary particles: The life span of particles varies from $10^{-16}$ to $10^{-24}$. By making use of their decay times, very small time intervals can be measured.
