Question

A simple pendulum makes 10 oscillations in 20 sec . what is the time period and frequency of its oscillations ?

Answer 1

• When a simple pendulum makes 10 oscillations in 20 seconds, the time taken for each oscillation = 20/10 = 2 seconds. Hence, as the time period is calculated to be 2 seconds, the frequency of oscillation = 1/T = 1/ 2 = 0.5 Hertz.
