JEE Main 2025 — 23 January, Morning Shift — Question 60

What is the lateral shift of a ray refracted through a parallel-sided glass slab of thickness ' hh ' in terms of the angle of incidence ' ii ' and angle of refraction ' rr ', if the glass slab is placed in air medium ?

  1. Option A:

    (htan⁡(i−r))/(tan⁡r)(h tan⁡(i-r))/(tan⁡r)

  2. Option B:

    htan⁡(i−r)tan⁡r\frac{h \tan (i-r)}{\tan r}

  3. Option C:

    h

  4. Option D:

    hsin⁡(i−r)cos⁡r\frac{h \sin (i-r)}{\cos r}

    Correct

Answer: D

Step-by-step solution

Formula base

hsin⁡(i−r)cos⁡r\frac{h \sin (i-r)}{\cos r}
