A pendulum oscillates 40 times in 4 seconds. Calculate its (i) time-period, and (ii) frequency. Can we hear the sound produced by the oscillations of this pendulum? Give reason for your answer.

Question

Philoid · Accepted Answer

Frequency = 40 vibration/ 4 seconds = 10 Hz

Thus, time period = 1/f = 1/10 = 0.1 seconds.

No, we cannot hear because the audible human range is from 20Hz to 20,000 Hz.
