SUMMARY
The index of refraction for the glass core of an optical fiber is 1.62, while the cladding has an index of 1.47. To determine the maximum angle a light ray can make with the wall of the core, the equation theta = sin-1(n2/n1) is used, yielding a critical angle of 65 degrees. However, since the question specifies the angle with the wall of the core, the correct angle is calculated as 90 - 65.15, resulting in a maximum angle of 24.85 degrees.
