Frequency and Time Period
Frequency (f)is the number of wave cycles passing a point per unit of time, measured in Hertz (Hz). Time Period (T)is the inverse concept: it's the time it takes for one full wave cycle to complete, measured in seconds (s). They are intrinsically linked by the formula:
$$ T=\frac{1}{f} $$
Wave Equation
The relationship between frequency (f), wavelength (λ), and wave speed (v) is described by the fundamental wave equation:
$$ v=f \cdot \lambda $$
This formula can be rearranged to solve for any variable:
- To find Frequency: $$ f=\frac{v}{\lambda} $$
- To find Wavelength: $$ \lambda=\frac{v}{f} $$
How to Use This Calculator
- The calculator has three primary input fields: Wavelength, Wave Speed, and Frequency.
- For Wave Speed, you can select from an extensive list of presets or choose "Custom Value" to enter your own.
- Enter values into any twoof the three primary fields.
- The third field will automatically become read-only, highlight in green, and display the calculated result.
- The Time Periodfield is always a result, calculated automatically whenever frequency is known.
- You can change the units for any field at any time, and all results will instantly update.
