Question

A simple pendulum oscillates 20 times in 2 seconds. Its frequency is

Answer 1

Frequency is no. of cycles / oscillation in 1 sec.

so 2 secs => 20 cycles

1 secs => 10 cycles

Hence frequency is 10 Hz

Answer 2

Answer:

The frequency of a simple pendulum is 10 oscillations per second.

Explanation:

The frequency of a repeated event is its number of occurrences per unit of time. It is different from angular frequency and is sometimes called a temporal frequency for clarification. The SI unit of frequency is hertz (Hz), or can also say one occurrence per second. The time elapsed between events is measured by the period, and the period is the reciprocal of the frequency.

Frequency is defined as the total number of oscillations in one second.

So,

number of oscillations in 2 seconds = 20

number of oscillations in 1 second = 20/2 = 10

Hence, the frequency of a simple pendulum is 10 oscillations per second.
