Convert to nanoseconds.

How long does it take for radiation from a cesium-133 atom to complete 1 megacycle?

I decided to submit a solution for you to check yours against
since no previous response was really an answer to your question


Since

1 second = 9,192, 631,770 cycles of the standard Cs-133 transition

we have that 1 cycle would be

...........1
▬▬▬▬▬▬▬▬ second
9,192, 631,770

multiply that number by 1,000,000
to determine the time in seconds to
complete a megacycle

and that is

0.000108783 second

Now since a nano second is
a billionth of a second, we can
multiply the above result by a billion
to convert it to nanoseconds

My result is

108782.7757
nanoseconds
or

108783 rounded to
the nearest nanosecond

One billionth of a second. So divide it by one billion.

Your question doesn't make sense.
