SUMMARY
A weakly damped harmonic oscillator exhibits a phase difference of approximately 90 degrees between the oscillator and the external periodic force at resonance. This phenomenon occurs due to the nature of driven harmonic motion, where the oscillator's response lags behind the driving force. The discussion emphasizes the importance of understanding this phase relationship for applications in physics and engineering, particularly in systems experiencing resonant oscillations.
