We observe interference pattern when the size of the slits are comparable to the wavelength of light. But here, the size of the bulb is bigger than wavelength of light.

Young’s double slit experiment is carried out using two bulbs in...
Explanation:
In Young's double slit experiment, interference fringes are observed due to the superposition of the two coherent waves from the two slits. If two bulbs are used instead of two slits and one source, the waves from the two bulbs will not be coherent and will not interfere constructively or destructively, resulting in no interference fringes.
The reasons for the absence of interference fringes are:
1. Incoherent sources: The light from two bulbs will be incoherent and not of the same frequency, phase or polarization. Hence, the waves from the two bulbs will not interfere constructively or destructively, resulting in no interference fringes.
2. Lack of coherence: The coherence length of the light from two bulbs is very short as compared to the distance between the bulbs. Due to this, the waves from the two bulbs will be out of phase and will not interfere constructively or destructively, resulting in no interference fringes.
3. No phase difference: In order to observe interference fringes, there should be a phase difference between the two waves. In the case of two bulbs, there will be no phase difference between the waves, resulting in no interference fringes.
Hence, the correct answer is option 'B' - No interference fringes will be observed.
