Two incoherent sources of light each with equal intensity `I_(0)` interfere in a medium . Will any interference pattern be observed ? If no, then why ? Also what would be resultant intensity then ?

Explanation

To solve the problem step by step, let's break it down:

### Step 1: Understanding Coherence
- **Explanation**: The first condition for observing an interference pattern is that the light sources must be coherent. Coherent sources emit light waves that have a constant phase difference and are monochromatic (of a single wavelength).
- **Hint**: Remember that coherence is essential for interference; without it, no pattern can form.

### Step 2: Identifying the Sources
- **Explanation**: In this case, the two light sources are described as incoherent. This means they do not maintain a constant phase relationship, which is crucial for interference to occur.
