Question

Light is incident normally in face AB of a prism as shown in figure A liquid of refractive index m is placed on face AC of the prism The prism is made of glass of refractive index 3/2 The limits of m for which total internal reflection takes place on face AC is

$μ > \frac{\sqrt{3}}{2}$
$μ < \frac{3 \sqrt{3}}{4}$
$μ > \sqrt{3}$
$μ > \frac{\sqrt{3}}{2}$

The correct answer is: $mu less than fraction numerator 3 square root of 3 over denominator 4 end fraction$
