Heya!!
For calculate period, lets applicate formula:
[tex]\boxed{T=1/f}[/tex]
Δ Being Δ
T = Period = ?
f = Frequency = 660 Hz
⇒ Let's replace according the formula:
[tex]\boxed{T=1/660\ Hz }[/tex]
⇒ Resolving
[tex]\boxed{T=0,0015\ s}[/tex]
Result:
The period of that wave is 0,0015 seconds.
Δ IMPORTANT Δ
The period is the INVERSE of the frequency. (T = 1 / f).
And the frequency is the inverse of the period (f = 1 / T)
Good Luck!!
