2.6
Skew rays are accepted into a large core diameter (compared with the wavelength of the transmitted light) step index fiber in air at a maximum axial angle of \( 42^{\circ} \). Within the fiber they change direction by \( 90^{\circ} \) at each reflection. Determine the acceptance angle for meridional rays for the fiber in air.
