Final answer:
In a highly damped system, the amplitude of the response decreases as the forcing frequency decreases due to the dissipation of energy.
Step-by-step explanation:
When damping is large and the system is not underdamped, the amplitude of the response decreases as the forcing frequency decreases. This is because damping refers to the dissipation of energy in the system, which causes the amplitude of the wave to gradually reduce to zero as time goes on. In the context of a harmonic oscillator, as described in the provided reference material, damping has the effect of decreasing the amplitude of the wave's motion. When we have a high amount of damping, it acts as a strong resistance to the motion and thus as the frequency of the driving force reduces, the amplitude of oscillation also decreases because the system cannot respond as effectively to slower changes in force.
When the damping is large (i.e., non-underdamped cases), the amplitude of the response decreases as the forcing frequency decreases. Damping refers to the dissipation of energy over time, which reduces the amplitude of the oscillation. In non-underdamped cases, the larger the damping, the more quickly the amplitude decreases.
