Correct option is A
The correct answer is:(A) 2.8 nanoseconds
Explanation:
The National Atomic Time Scale (NATS), which was dedicated to the nation by Prime Minister Modi in January 2021, has an accuracy level of 2.8 nanoseconds.
This time scale will serve as a crucial component for the Indian Standard Time (IST) and is part of India's efforts to enhance its scientific capabilities and time synchronization.
The NATS is based on a network of atomic clocks and plays a vital role in activities such as satellite navigation and telecommunication.
Additional knowledge:
- Atomic clocks are highly precise and measure time based on the vibrations of atoms (commonly cesium or rubidium).
- The 2.8 nanosecond accuracy means that the National Atomic Time Scale can measure time with an extremely small margin of error, providing highly reliable and synchronized time.
- The development of NATS enhances India's ability to meet the global standards of timekeeping, especially in areas like GPS services, communications, and defense operations.
