(9.4) Real values of the critical angle occur only when V, 1). This effect occurs for any angles of incidence greater than the critical value (defined in Fig.
The incident wave experiences total internal reflection, and the transmitted wave is called evanescent (Fig. This item is available to borrow from 2library branches.
