Question

a pendulum oscillates 4 times in 40 seconds find its time period and frequency

​

Answer 1

$\huge\sf\red{SoLution!!...}$

Time period...

✰✰ The time required to complete 1 oscillation is known as Time Period...

So, It is given by the inverse of frequency...

• $\:Time \:period\: = \dfrac{time}{frequency\:of\: oscillation}$

Time period = $\dfrac{4}{40}$

$\boxed{\green{\underline\textbf{0.1 sec...}}}$

Answer 2

It can be given by : The reciprocal of frequency is called time period. So, Hence, time period is 0.1 seconds and frequency is 10 Hz.
