Speed of a sound wave in water is `1600ms^(-1)` and its frequency is 4000 Hz. Find time period of the wave.

Explanation

To find the time period of a sound wave given its frequency, we can use the relationship between time period (T) and frequency (f). The time period is the reciprocal of the frequency.

### Step-by-Step Solution:

1. **Identify the given values:**
- Speed of sound wave in water: \( v = 1600 \, \text{m/s} \) (not needed for this calculation)
- Frequency of the sound wave: \( f = 4000 \, \text{Hz} \)
