Q. With reference to the atomic clock, consider the following statements:
1.It is a clock that measures time by monitoring the resonant frequency of atoms.
2.It uses radioactive decay to capture the time interval and hence they are more accurate than quartz clock.
Which of the statements given above is/are correct?

[A] 1 only

[B] 2 only

[C] Both 1 and 2

[D] Neither 1 nor 2

Answer: C
Notes:

Atomic clock measures time by monitoring the resonant frequency of atoms. The atom clocks use radioactive decay to capture the time interval and hence they are very accurate.
