Answer 1

Question

A pendulum makes 27 oscillations in 3 seconds. What is the frequency of the pendulum?

Answer

In 3 seconds pendulum makes = 27 oscillation

In 1 second pendulum makes = 27 ÷ 3 = 9

So,the frequency of the pendulum is 9 oscillation or 9 Hertz (Hz)

Other information

• The too and fro motion is called oscillation
• SI unit of oscillation is Hertz.
• Its symbol is Hz.
• SI unit of period is second.
• Study of frequency is called cymatics.

Answer 2

Answer:

In 3 seconds pendulum makes = 27 oscillation

In 1 second pendulum makes = 27 ÷ 3 = 9

So,the frequency of the pendulum is 9 oscillation or 9 Hertz (Hz)
