The figure shows a ray of light entering and passing through a dense glass slab and emerging from the other side. If the angle of incidence $i=60^{\circ}$, slab thickness $b=0.04 \text{ m}$, and the refractive index of glass $\mu=\sqrt{3}$, the parallel shift $d$ between the emerging and entering rays in $\text{mm}$ is:

  • A
    $\sqrt{\frac{3}{4}}$
  • B
    $\sqrt{\frac{4}{3}}$
  • C
    $\frac{40}{\sqrt{3}}$
  • D
    $15 \sqrt{3}$
