I should mention that the frequency should have units of Hz (hertz) or
s
−
1
and the period should have units of seconds.
The frequency is known and the units are good. All we have to do is rearrange the equation to solve for T:
We want T to cancel out on the right side:
T
×
f
=
1
T
×
T
T
×
f
=
1
Divide both sides by f to get T by itself:
T
×
f
f
=
1
f
Thus,
T
=
1
f
Now we can solve for the period:
T
=
1
25
H
z
0.04s
