Practice NEB Class 12 Oscillations in the app →A plucked guitar string repeats the same vibration over and over. Such motion is called:The SI unit for frequency, meaning one cycle per second, is the:The time taken for one complete oscillation is called the:A wave whose oscillation follows Hooke's law is described as simple:A guitar string plucked hard and plucked gently sounds the same note because the period is:Only two things set the period of a mass on a spring: the force constant and the:A stiff spring has a large force constant, which makes the period:The period of a simple pendulum depends on gravity and on its:Two pendulums differ only in the mass of the bob. On the period, that mass has an effect that is:Knowing a pendulum's length precisely lets a physicist measure the local acceleration due to:In a lightly damped oscillator, the period stays about the same but the amplitude gradually:A damped oscillator loses energy because the work done by the damping force is:A system returning to equilibrium in the shortest time without overshooting is:A system that creeps slowly back to equilibrium has damping described as:A system that reaches equilibrium quickly but oscillates about it is described as:Driving a system at its natural frequency, so the amplitude grows large, produces:The distance between adjacent identical parts of a wave is its:A wave whose disturbance is perpendicular to its direction of travel is:A wave whose disturbance is parallel to its direction of travel is:Two identical waves arrive crest on crest, so the amplitude of the result is:Two identical waves arrive crest on trough, so the amplitude of the result is:Two waves of slightly different frequencies but equal amplitude combine to produce:
