Q: If a forced oscillator is driven at a frequency much lower than its natural frequency, what happens to the amplitude?
Solution: At frequencies much lower than the natural frequency, the amplitude of the forced oscillator increases significantly.
Steps: 5
Step 1: Understand what a forced oscillator is. A forced oscillator is a system that is being driven by an external force at a certain frequency.
Step 2: Know what natural frequency means. The natural frequency is the frequency at which the system would oscillate if it were not driven by an external force.
Step 3: Identify the relationship between the driving frequency and the natural frequency. In this case, the driving frequency is much lower than the natural frequency.
Step 4: Recognize that when the driving frequency is much lower than the natural frequency, the system can respond more easily to the external force.
Step 5: Conclude that as a result, the amplitude of the forced oscillator increases significantly because it can oscillate more freely.
