Frequency Calculator
Calculate frequency from period (f = 1/T) or wavelength (f = v/λ). Supports both modes.
How to Use the Frequency Calculator
- Select the mode: from period or from wavelength.
- Enter the period (seconds) or wavelength (meters).
- Click Calculate to find the frequency.

Fórmula
f = 1/T (from period) or f = v/λ (from wavelength), where f is frequency (Hz), T is period (s), v is wave speed (m/s), λ is wavelength (m).
Perguntas Frequentes
What wave speed is used for wavelength mode?
The calculator uses 343 m/s (speed of sound in air at 20 °C). For light, use the wavelength calculator instead.
What is the relationship between frequency and period?
Frequency and period are reciprocals: f = 1/T and T = 1/f.
