A right angled glass prism is shown in the figure. A liquid film is in contact with the hypotenuse face. A ray of light incident normally on the face $\mathrm{AB}$ will undergo total internal reflection from the hypotenuse face, if the refractive index of the liquid is $\left[\mu_{\text {glass }}=\frac{3}{2}\right]$
