Geometrical Optics — JEE Advanced Previous Year Questions

How many JEE Advanced questions come from Geometrical Optics?

Geometrical Optics has contributed 33 questions to Joint Entrance Examination (Advanced) papers between 2016 and 2026 — an average of about 3 questions a year. That count is measured from EByAi’s bank of 18,502 JEE Advanced questions, not estimated from a syllabus. Every one of the 33 questions carries a written, step-by-step solution, and each is tagged to Geometrical Optics within Physics, so you can drill this chapter across every year at once instead of hunting through paper PDFs. Practising a chapter’s full PYQ history is the fastest way to learn the patterns examiners reuse.

1. Question 1 · JEE Advanced 2026

   A beam of polychromatic light passes through a thin prism of prism angle $6^{\circ }$. The refractive index of the material of the prism varies with wavelength $(\lambda )$ as $n(\lambda )=\alpha \lambda +\frac{\beta }{{\lambda }^2}$, where $\alpha =3\mu m^{-1}$ and $\beta =0.096\mu m^2$. If ${\lambda }_{min}$ is the wavelength at which the angle of minimum deviation $D_m$ is smallest, then the correct value of $D_m$ at ${\lambda }_{min}$ is :
   1. (A)6.4°
   2. (B)4.8°
   3. (C)3.2°
   4. (D)2.4°
