Question:
A glass optical fiber "captures" a ray of light by imposing total internal reflection upon that ray, many times over. Once inside the glass, such a ray will undergo total internal reflection if it strikes the boundary between glass and air at an angle of incidence that is greater than the critical angle.
Suppose that an optical fiber is flat on one end, with the end surface at right angles to the fiber's long axis, as shown.
