A pendulum oscillates 40 times in 4 seconds. Find its time period and frequency.

Explanation

To solve the problem of finding the time period and frequency of a pendulum that oscillates 40 times in 4 seconds, we can follow these steps:

### Step 1: Understand the Definitions
- **Frequency (f)** is defined as the number of oscillations (or cycles) per unit time. It is measured in hertz (Hz), where 1 Hz = 1 oscillation per second.
- **Time Period (T)** is the time taken for one complete oscillation. It is the reciprocal of frequency, given by the formula:
\[ T = \frac{1}{f} \]
