What is the basic relation between frequency and time period?

[tica86]

I don't have a homework question I just wanted to try and understand the relationship between time and frequency for example when f=2.0 Hz, T=0.5 seconds or when f=0.5 Hz, T=2.0 seconds

if I were only give T=2.0 seconds how do I know what f is??

 

[The legend]

there is a basic relation actually.

F=1/T
