Hello!

Data:

T (period) = 12 s

f (frequency) = ? (waves/second)

Formula:


f = (1)/(T)

Solving:


f = (1)/(T)


f = (1)/(12)


\boxed{\boxed{f \approx 0.083\:waves/second}}\end{array}}\qquad\quad\checkmark

Use your units !
"Period" is time . . . 12 seconds.
"Frequency" how often . . . " ___ PER time". Time is in the denominator.

"12 seconds per wave" means

1 wave / 12 seconds

= ( 1 / 12 ) (wave/second)

= 0.08333... wave per second

= 1/12 Hz.
