JEE Main 4 April 2024, Shift 2, Physics Q52

Question 52 of 90 in this shift, Physics question 22 of 30, Section B.

A light ray is incident on a glass slab of thickness 434\sqrt{3} cm and refractive index 2\sqrt{2}. The angle of incidence is equal to the critical angle for the glass slab with air. The lateral displacement of ray after passing through glass slab is ______ cm. (Given sin⁡15∘=0.25\sin15^\circ = 0.25)
