Question

A pendulum oscillates 50 times in 2 seconds. Find its time period and frequency

Answer 1

Time period: Time taken for one oscillation
T = 2 / 50 = 0.04 seconds

Frequency: Total oscillations in one second
f = 50 / 2 = 25 Hz

Answer 2

Time period =Time taken by the pendulum to compete one to and fro motion .
Time period=Time/no.of oscillation
=2/50=0.04 sec
frequency=oscillation in time taken by pendulam
frequency=no. of oscillation/time
=50/2
=25
