A Young's double slit experiment uses a monochromatic light of wavelength `lambda`. The intensity of each slit is same and is equal to `I_(0)`. What will be the resultant intensity at a point where waves interfere at a path difference of `(lambda)/2` ?

Explanation

To solve the problem, we will follow these steps:

### Step 1: Understand the Setup
We have a Young's double slit experiment with monochromatic light of wavelength \( \lambda \). The intensity of light from each slit is \( I_0 \).

### Step 2: Identify the Path Difference
The problem states that we need to find the resultant intensity at a point where the path difference between the two waves is \( \frac{\lambda}{2} \).
