A glass rod having square cross-section is bent into the shape as shown in the figure. The radius of the inner semi-circle is R and width of the rod is d. Find the minimum value of `d//R` so that the light that enters at A will emerge at B. Refractive index of glass is `mu=1.5`

A rod of glass ( mu = 1.5) and of square cross section is bent into the shape shown in the figure. A parallel beam of light falls on the plane flat surface A as shown in the figure.
