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

AcademicPhysicsNCERTClass 8

Here given, no. of oscillations $=10$

time $=20\ s$

So, time period $T=\frac{time\ taken}{no.\ of\ oscillations}$

$=\frac{20\ s}{10}$

$=2\ s$

So, frequency, $f=\frac{1}{T}$

$=\frac{1}{2\ s}$

$=0.5\ Hz$

Therefore, the time period is $2\ s$, and the frequency is $0.5\ Hz$.
