Question

Which type of phenomenon can be used as a measure of time? Give 3 example?

Answer 1

hi frnd the answer is
Any phenomenon that repeates itself regularly at equal intervals of time can used to measure time.
The examples are:
(i) Rotation of earth—The time interval for one
complete rotation is called a day.
(ii) Oscillations of a pendulum.
hope it helps.

Answer 2

Any phenomenon that repeats itself regularly at equal intervals of time can be used to measure time.

• We can live time intervals — the period between 2 events.
• Most accurately with atomic clocks.
• These clocks manufacture radiation, like microwaves, with an explicit frequency that causes atoms within the clock to leap from one energy to a different.
• Metal atoms build such quantum jumps by fascinating microwaves with a frequency of nine,192,631,770 cycles per second, which then defines the international scientific unit for time, the second.
