A light ray is incident on a glass slab of thickness 4 3 ~cm and refractive index 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 . 15^ =0.25 )

Correct answer

0

Step-by-step solution

aligned & i= _c & i= ⁻¹ ( 1 ) & i=45^ aligned and according to snell's law aligned & 1 45^ = 2 r & r =30^ aligned Lateral displacement = t ( i - r ) r aligned & = 4 3 15^ 30^ & =2 ~cm aligned
