Questions & Step-by-Step Solutions
In a forced oscillation, what is the effect of resonance?
Step 1: Understand what forced oscillation means. It is when an external force causes an object to vibrate.
Step 2: Know what resonance is. It happens when the frequency of the external force matches the natural frequency of the object.
Step 3: Recognize that every object has a natural frequency at which it vibrates best.
Step 4: When the driving frequency (the frequency of the external force) matches the natural frequency, the object starts to vibrate more strongly.
Step 5: This matching of frequencies causes the amplitude of the vibrations to increase significantly.
Step 6: In simple terms, at resonance, the object shakes a lot more than it normally would because the external force is perfectly timed with its natural vibrations.
