Question

a bob vibrates up and down on a vertical spring. if the period of the motion is two seconds, the frequency is: two seconds. i took f=1/period=1/2
You are correct.

Frequency = 1/(period), which in your case is 1/2 cycles per second, or 0.5 Hz.

Cycles per second is called Hertz (abbreviated Hz).
