Period vs Frequency
Formule
Wave Period
The period is the time for one complete cycle of a wave.
Formulas
T = 1 / f
The angular frequency is omega = 2 * pi * f, measured in radians per second.
Exemple Résolu
A 60 Hz electrical wave (common AC frequency).
- 01T = 1 / f
- 02T = 1 / 60
- 03T = 0.01667 s = 16.67 ms
- 04omega = 2 * pi * 60 = 376.99 rad/s
Questions Fréquentes
What is the period of a 440 Hz sound wave?
T = 1/440 = 0.00227 seconds, or about 2.27 milliseconds.
What is angular frequency?
Angular frequency (omega) expresses the rate of oscillation in radians per second. One full cycle = 2*pi radians, so omega = 2*pi*f.
Why is AC electricity 50 or 60 Hz?
These frequencies were chosen as engineering compromises. 60 Hz is standard in North America; 50 Hz is used in most of the rest of the world.
