Wave Period Calculator (T = 1 / f)
Computes cycle time period T = 1 / f for waves, pendulums, and rotating mechanical systems.
Universal Wave Mechanics Calculator
Calculate speed, frequency, period, and wavelength via v = f · λ.
Wave Presets:
Sinusoidal Wave ProfilePeriod T = 2.27 ms
Wavelength (λ)
0.7795 m
Period (T = 1/f)2.273 ms
Angular Freq (ω)2764.6 rad/s
Wavenumber (k)8.06 rad/m
Speed (km/h)1234.8 km/h
Step-by-Step Derivation
1. Wave Equation: λ = v / f
2. Substitution: λ = (343 m/s) / (440 Hz)
3. Wavelength: λ = 0.7795 meters (77.95 cm)
4. Period: T = 1 / f = 1 / 440 = 2.273 ms
5. Angular Frequency: ω = 2πf = 2764.60 rad/s | Wave Number: k = 2π/λ = 8.06 rad/m
What is a Wave Period?
