tude decays to $ 1 / e $ of its original value? 66. A harmonic oscillator is underdamped if the damping constant $ b $ is CH less than $ \sqrt{2} m \omega_{0} $, where $ \omega_{0} $ is the natural frequency of undamped motion. Show that for an underdamped oscillator, Equation 13.19 has a maximum at a driving frequency less than $ \omega_{0} $.
