JEE Main 24 June 2022, Shift 2, Physics Q57

Question 57 of 90 in this shift, Physics question 27 of 30, Section B.

A ray of light is incident at an angle of incidence 60∘60^{\circ} on the glass slab of refractive index 3\sqrt{3}. After refraction, the light ray emerges out from other parallel faces and lateral shift between incident ray and emergent ray is 434\sqrt{3} cm. The thickness of the glass slab is _______cm.
