SUMMARY
The discussion focuses on calculating the critical angle and minimum angle of incidence for light traveling from ice (refractive index 1.3) to air. The critical angle, calculated using the formula sin(θc) = 1/n, results in θc = 50.3 degrees. For the minimum angle of incidence required for light to refract out of the ice block, participants suggest drawing a diagram to clarify the problem. The consensus is that the minimum angle does not need to be applicable at every point along the surface, but rather at some point.
