Question

A simple pendulum completes oscillations in one minute. Find its (a) frequency, (b) time period.

Answer 1

Given: oscillations = 40
Time taken $=1minute$

or $60s$

(a) In one second the frequency is 40/60 $=0.67hz$

(b) Frequency$=1/timeperiod$
$\therefore$ time period $=1/frequency$
$=1/0.67$
$=1.5s$
