Question 2
A student investigates the energy transfer in a driven harmonic oscillator by measuring the amplitude of oscillation at different driving frequencies. The oscillator has a natural frequency of 8.5 Hz. The graph below shows the relationship between amplitude (mm) and driving frequency (Hz). Describe the mathematical relationship between amplitude and driving frequency shown in the graph.
