How can I find time, given the frequency?

[TaintedLove]

I know frequency = 1/t, but is that in every case? In our momentum lab, we were given that the frequency is 1/50... does that mean the time is 50s?

Frequency is usually given in Hertz: Hertz = 1/s
But using any units, yes it is 1/t.

You can think of it as "cycles/second" if you want (or any other time unit), but we just don't write units for cycles.
So yes it is for every case. the t is usually T which stands for the period, you just need to decide in every case what T is measuring.
Usually how long it takes for a wave to repeat itself.
