Forced oscillation and resonance

Principle

In the Experiment "Helical spring pendulum" the students have determined the natural frequency of a spring pendulum and established this frequency dependence on pendulum mass and spring constant. In this experiment they should force a spring pendulum to oscillate and from observations of the forced oscillation amplitude make conclusions concerning the correlation between excitation frequency and natural frequency.
Furthermore, the natural frequency of a spring pendulum should be measured and then compared with the (approximate) natural frequency determined in the second part of the experiment.
