Question

Diffrnt kate quartz clock and atomic clock

Answer 1

$\large{\underline{\underline{\textsf{{\blue{Answer :- }}}}}}$

An electronic circuit converts this exact frequency into one-per-second pulses that can be used to drive a relatively ordinary quartz clock mechanism with amazing accuracy. "Amazing" in this case means just that: the best atomic clocks are accurate to within 2 nanoseconds per day, or one second in 1.4 million years!

Answer 2

Explanation:

Atomic clocks are actually quartz clocks—just like the ones you have at home. The difference is that an ordinary quartz clock relies purely on the oscillations of its quartz crystal to count seconds.
