Question

. If 200 oscillations are produced in 10 seconds, what is the frequency and time period ?​

Answer 1

Answer:

Simple Pendulum is a very small heavy metal bob suspended at a point from a firmly fixed support using a single strand thread so that it oscillates freely. The distance between the point of suspension and centre of bob is called the length of the pendulum.

One oscillation: One complete to and fro motion of the oscillating body is called one oscillation.

Frequency: It is the number of oscillations made by the body in one second.

Time Period: It is the time taken by a body to complete one oscillation.

Hence, the Frequency and Time period are calculated as follows.

Time period = Time taken by the pendulum/Number of oscillations made by the pendulum.

$\frac{10}{200} = > \frac{1}{20} = > 0.05 \: seconds$

Frequency =1/Period

$\frac{1}{0.05} = > \frac{100}{5} = > 20hz$

Hence, the Time period and frequency are 0.05 seconds and 20 Hertz respectively.
