A train whistle blows every 10 seconds. What is the frequency of the whistle?
Frequency is inversely proportional to time period, so:
So the frequency is
This is because Hertz, or frequency is defined as "events per second". As there is 1 event every 10 seconds it has a frequency of
Since the train whistle blows every
Frequency is inversely proportional to period, and the equation is:
#T#is the period in seconds
So here, the frequency will be
