WebIn general, total internal reflection takes place at the boundary between two transparent media when a ray of light in a medium of higher index of refraction approaches the other … WebNov 25, 2015 · The critical angle comes into play when you consider where the peak of the wave is on the boundary between two mediums. If θ is the angle between the wave direction and the surface normal and v is the speed of the wave, this point travels at a speed csc ( θ) v. This makes sense: if θ = π / 2, the point at the boundary is just the wave speed. inyecter
