A beam of light enters the end of an optic fiber as shown
Chapter 23, Problem 40(choose chapter or problem)
A beam of light enters the end of an optic fiber as shown in Fig. 23–58.
\((a)\) Show that we can guarantee total internal reflection at the side surface of the material (at point A), if the index of refraction is greater than about 1.42. In other words, regardless of the angle \(\alpha\), the light beam reflects back into the material at point A, assuming air outside.
\((b)\) What if the fiber were immersed in water?
