About Frequency Calculator
The Wave & Oscillatory Frequency ($f = 1/T$) Calculator computes wave frequency, oscillation period ($T$), angular frequency ($\omega = 2\pi f$), electromagnetic wave speed ($v = f\lambda$), LC resonant tank frequency ($f_0 = \frac{1}{2\pi\sqrt{LC}}$), and musical pitch note frequency (A4 = 440 Hz standard).

Key Terminology & Definitions
Frequency ($f$)
The number of complete oscillatory cycles or wave crests passing a fixed point per second, measured in Hertz ($\text{Hz} = \text{s}^{-1}$).
Angular Frequency ($\omega$)
The rate of change of phase of a sinusoidal waveform, measured in radians per second ($\omega = 2\pi f$).
