Question

if the time period of oscillation of a pendulum Is 5 seconds then calculate it's frequency ​

Answer 1

Answer:

Frequency is the reciprocal of the period. The period is 5 seconds, so the frequency is 1/(5 s) = 0.20 Hz.

Answer 2

That time period (T) of an oscillating body, like a pendulum, is the time spent in completing one full oscillation. The frequency (f) is the number of oscillations performed in one second. Mathematically, the frequency is the reciprocal of the time period. If T=5 seconds then f=
