  <h3>Resonance</h3>
  <p>Resonance occurs when an external force is applied to a system at its natural frequency, causing it to vibrate with increased amplitude. This phenomenon is commonly observed in musical instruments, where the strings or air columns vibrate at specific frequencies to produce distinct sounds.</p>
  
  <h3>Applications</h3>
