The **time period of a pendulum clock** depends on the **length of the pendulum**. The time period is the time it takes for the pendulum to complete one full swing, or one oscillation.

The time period of a simple pendulum can be calculated using the formula:

T = 2π√(L/g)

Where T is the time period, L is the length of the pendulum, and g is the acceleration due to gravity (approximately 9.81 m/s^2).

For example, if the length of the pendulum is 1 meter, then the time period would be:

T = 2π√(1/9.81) ≈ 2.006 seconds

Therefore, for a pendulum clock with a pendulum of** length 1 meter**, the time period would be approximately** 2 seconds**. In practice, pendulum clocks are typically designed with a pendulum length that results in a time period of one second, making it easier to measure time accurately.

**Q. The time period of a pendulum clock (Length of 1 Meter) is**

(A) 1 second

(B) 2 second

(C) 1 minute

(D) 1 hour

(E) None of the above/ More than one of the above

**Ans: (B)**

**Solution**: The time period of oscillation of a wave is defined as the time taken by any element of the string to complete one such oscillation. A pendulum clock takes 1 second to move from one extreme to the other extreme. As a result, one oscillation takes 2 seconds.
