Question

If a pendulum makes 14 oscillations in 3 seconds. Find out its time period and frequency.

Answer 1

total time taken
__________ =. 14
no.of oscillations. 3

Answer 2

Given that 40 oscillations are made by the pendulum for 4 sec.

So, It makes 10 oscillations are made by the pendulum for 1sec.

We know that the number of oscillations made per second (10 oscillations per second ) is called its frequency

∴ Frequency = 10 Hz

Time period = 1/ Frequency

Time period = 1/ 10

Time period = 0.1 sec
