Example data table
| Scenario | Inputs | Method | Period (s) |
|---|---|---|---|
| Lab oscillator | f = 2 Hz | T = 1/f | 0.5 |
| Rotating source | f = 120 rpm | T = 1/f | 0.5 |
| Angular description | ω = 4π rad/s | T = 2π/ω | 0.5 |
| Wave on a string | λ = 1.5 m, v = 3.0 m/s | T = λ/v | 0.5 |
| Longer period swell | f = 0.1 Hz | T = 1/f | 10 |
These examples are rounded for readability.
Formula used
- Period and frequency:
T = 1 / f - Period and angular frequency:
T = 2π / ω - Period from wavelength and speed:
T = λ / v - Wave relation:
v = fλ(for periodic waves)
The calculator converts your selected units into SI, applies the chosen relation, then formats results using your significant-figure setting.
