The image shows a page from a book discussing the refractive index of a glass prism. It includes a graph illustrating the relationship between deviation (d') and incident angle (i) or emergent angle (e), with specific points labeled $i_1$ and $i_2$. Below the graph, there is a special case equation: $i = \frac{1}{2}(dm + A)$ and $r = \frac{A}{2}$. The text then states that the refractive index (n) is given by $n = \frac{Sin\ i}{Sin\ r}$ and provides a specific formula for $n$ in terms of minimum deviation ($D_{min}$) and the prism angle (A): $n = \frac{Sin\ \frac{(A+D_{min})}{2}}{Sin\ \frac{A}{2}}$. The final sentence instructs the reader to find $d_m$, A, and hence determine the refractive index of the glass prism from appropriate graphs. There is a page number "34" at the bottom.
