What does this formula means:
f = 1/T I don't get this. Please explain the relationship between frequency and period and the formula above thanks :)

Using different units in that example obscures the relationship a bit. A frequency of 120 beats per minute corresponds to a period of 1/120 of a minute per beat. Continuing, 1/120 of a minute = 1/2 second.
Or to match the original formula better: a period of 1/2 second per beat corresponds to a frequency of 1/(1/2) beats per second = 2 beats per second. Continuing, 2 beats per second = 120 beats per minute.

f = 1/T?? What does it mean?
agree with jtbell, bad example from wiki. It's simple math, threy. If you tnink about it the same way you think of ax=b there is no confusion. The trick is that T is time for 1 oscilation, so ax=b becomes ax=1.

It simply means frequency is inversely proportional to time taken to complete one oscillation
and proportionality constant is 1

The frequency f is the number of cycles per second. The period T is the number of seconds per cycle.

You've done this before, haven't you

If you can walk around the block in 1/2 hour, (30 minutes) then you can do it 2 times in one hour.
If you can walk around the block in 1/3 hour (20 minutes) then you can do it 3 times in one hour. If you can walk around the block in 1/4 hour (15 minutes) then you can do it 4 times in one hour. If you can walk around the block in 1/10 hour (6 minutes) then you can do it 10 times in one hour.
