What type of interference pattern will be observed if two light sources of same wavelengths are used in Young's double-slit experiment ?

Explanation

To determine the type of interference pattern observed when using two light sources of the same wavelength in Young's double-slit experiment, we can follow these steps:

### Step-by-Step Solution:

1. **Understanding the Setup**:
In Young's double-slit experiment, two slits (S1 and S2) are illuminated by light. The light waves emerging from these slits overlap and create an interference pattern on a screen.

2. **Single Source vs. Two Sources**:
