Question: If a forced oscillator is driven at a frequency much lower than its natural frequency, what happens to the amplitude?

Options:

Correct Answer: Decreases

Solution:

At frequencies much lower than the natural frequency, the amplitude of the forced oscillator increases significantly.

If a forced oscillator is driven at a frequency much lower than its natural frequency, what happens to the amplitude?

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.

Forced Oscillation – A forced oscillator is a system that is driven by an external periodic force, and its response depends on the relationship between the driving frequency and the natural frequency of the system.
Natural Frequency – The natural frequency is the frequency at which a system tends to oscillate in the absence of any driving force.
Amplitude Response – The amplitude of a forced oscillator varies with the frequency of the driving force, particularly increasing significantly when the driving frequency is much lower than the natural frequency.
