Radio waves, infrared, visible light, ultraviolet, X-rays, and gamma rays are examples of waves conveyed by simultaneous periodic fluctuations in electric and magnetic field intensity.

Resonance is a phenomenon in which the frequency of a wave is the same as the system's natural frequency. The frequency is referred to as resonant frequency.

The resonant frequency of an LCR circuit is

$f_0=\frac{1}{2\mathrm{Ï€}\sqrt{LC}}$

Where $f_0$is the resonant frequency, L s inductance, and C is the capacitance

Radio tuning is an example of resonance. AnLCRcircuit with variable C is included in the tuning circuit of a radio receiver. It varies until the circuit's frequency is equivalent to the frequency of another radio station.

This signal's current is at its highest, and the receiver responds to it.
