Hey guys, im trying to understand a physics question. It reads,

A vibrating spring moves from its position of maximum elongation to its position of maximum compression in 1 second. What is the frequency of the oscillations?

The answer is:

f=1/T
=1/2
=0.5 Hz

It says that if this takes 1 sec, then the time required for a complete cycles is 2s. I am so lost at how T equals 2 seconds. Please help me.

A cycle is defined as something moving from it's starting point and back again.

The question gives the distance only to move one half of a cycle - so you need to multiply it by two to get the length of a full cycle - and the length of a full cycle is T, the period.
