Resonance

• Resonance is the tendency of a system to vibrate at maximum amplitude at certain frequencies
• The wave and the object have to be at the natural frequency of the object for the object to vibrate.
• Multiple systems can vibrate at the same frequency
• Resonance causes a larger amplitude and intensity of the wave.
• e.g. Instruments use resonance to sound louder
• e.g. MRI machines use resonance to make images
