Two sound waves, originating from the same source, travel along different paths in air and then meet at a point. If the source vibrates at a frequency of 1.0 kHz and one path is 83 cm longer than the other, what will be the nature of interference? The speed of sound in air is `332 ms^-1`.

Explanation

To determine the nature of interference between two sound waves that meet at a point, we can follow these steps:

### Step 1: Identify the given values
- Frequency of the sound wave, \( f = 1.0 \, \text{kHz} = 1000 \, \text{Hz} \)
- Extra distance traveled by one wave, \( \Delta x = 83 \, \text{cm} = 0.83 \, \text{m} \)
- Speed of sound in air, \( v = 332 \, \text{m/s} \)

### Step 2: Calculate the wavelength (\( \lambda \))
