Two coherent sources each emitting light of intensity `I_(0)` Interfere, in a medium at a point, where phase different between them is `(2pi)/3`. Then, the resultant intensity at that point would be.

Explanation

To find the resultant intensity at a point where two coherent sources are emitting light with a phase difference of \( \frac{2\pi}{3} \), we can use the formula for the resultant intensity due to interference of two coherent sources.

### Step-by-Step Solution:

1. **Understand the Given Information**:
- Each source emits light with intensity \( I_0 \).
- The phase difference \( \phi \) between the two sources is given as \( \frac{2\pi}{3} \).
