E)the maximum value of the sine is 1.5.

Question

The condition for total internal reflection occurs when the angle of incidence exceeds the critical angle, which is determined by Snell's law. The critical angle is found when the sine of the angle of refraction is 1.0, as the sine function cannot exceed 1.0.
