Which of the following technique is not used for measuring small time intervals?

Step-by-step solution

Time measurement techniques are classified based on the physical phenomena involved. Electronic oscillators, such as quartz crystal oscillators, are used for precise timekeeping in electronic devices. Atomic clocks utilize the vibrations of atoms, such as cesium-133, to measure time with extreme precision. The decay of elementary particles is a fundamental process used in particle physics to measure extremely short time intervals. A spring oscillator, while periodic, is subject to significant damping, friction, and
