Period Calculator
Calculate the period of a wave or oscillation from its frequency. T = 1/f. Also calculates period of a pendulum.
Enter frequency or pendulum length.
Period Formulas
T = 1/f (from frequency)
T = 2π√(L/g) (simple pendulum)
T = 2π√(L/g) (simple pendulum)
Example: f = 50 Hz → T = 1/50 = 0.02 seconds
Pendulum L = 1 m → T = 2π√(1/9.81) ≈ 2.006 s
Pendulum L = 1 m → T = 2π√(1/9.81) ≈ 2.006 s
