When a person sitting on a swing stands up on the swing, the frequency of oscillation – (1) decreases (2) increases (3) becomes infinite (4) does not change
(2) increases Explanation: In Simple Harmonic Motion, the frequency of the oscillation (1) is the number of oscillations per second which is expressed as f = 1/T where T is the time period (the time for the oscillator to complete one cycle).
