Physics · Oscillations and Waves
Consider the following statements for resonance in a forced damped harmonic oscillator and choose the correct option: Statement (A): The amplitude resonance occurs when the driving frequency is slightly lower than the natural frequency of the oscillator, depending upon the magnitude of damping. The velocity resonance occurs when the two frequencies are exactly equal, whatever the damping may be. Statement (B): At amplitude resonance, the displacement lags behind the driving force by π, while the velocity at resonance is always in phase with the driving force.
