    A ray of light is incident from air on a glass plate having thickness 3 cm\sqrt{3}\text{ }cm and refractive index 2\sqrt{2}. The angle of incidence of a ray is equal to the critical angle for glass-air interface. The lateral displacement of the ray when it passes through the plate is ____\_\_\_\_ ×10−2 cm\times10^{- 2}\text{ }cm. (given sin⁡15∘=0.26\sin15^{\circ}= 0.26 )

    A light ray is incident on a glass slab of thickness 43 cm4\sqrt{3}\text{ }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 ______ cmcm. (Given sin⁡15∘=0.25\sin15^{\circ}= 0.25 )
