Find Required Slit Thickness t For Central Maxima at O | Wave Optics | Allen SCORE 2 | JEE Adv 2026

In this video, we solve a high-level Wave Optics problem from Allen SCORE-2 based on a modified Young’s Double Slit Experiment (YDSE).

A monochromatic source of wavelength 42 Å is used. Different refractive index media are present on both sides of the slits, and one slit has a varying refractive index.

The key question:

👉 What should be the required thickness
𝑡
t of the slit so that the central maximum occurs at point O?

This problem beautifully tests:

Optical Path Length concept

Central maxima condition in YDSE

Effect of refractive index on phase difference

Advanced interference reasoning

Perfect for JEE Advanced 2026 aspirants.

If you want strong conceptual clarity in Wave Optics, this is a must-solve problem.
