Pendulum A makes 15 oscillations in 5 seconds and Pendulam B makes 8 oscillations in 4 seconds . Which has higher frequency ?

Dear Student,
Please find below the solution to the asked query:

Frequency = No. of oscillations/ Total time

Frequency of pendulum, A = 15/5 = 3 Hz

Frequency of pendulum, B = 8/4 = 2 Hz

Hence, pendulum A has high frequency than that of pendulum B.

Pendulum A makes 15 oscillations in 5 sec

Then it will make 15 *12 in  60 sec

180 oscillations in 60 sec
 
Frequency = 60 / 180 = 1/3 Hz = 0.3333Hz


Pendulum B = 8 oscillations in 4 sec

8 * 15 in 60 sec

= 120 oscillations in 60 sec= 60 / 120 = 0.5 Hz

So Pendulum A had=s higher frequency
