TOTAL INTERNAL REFLECTION

If the angle of incidence is further increased beyond the critical angle, then ray instead of being refracted gets totally internally reflected according to law of reflection. This phenomenon is called 'TOTAL INTERNAL REFLECTION". 

CONDITIONS FOR TOTAL INTERNAL REFLECTION : 

1- The ray must passes from a denser to a rarer medium.

2- The angle of incidence in the denser medium must be greater than the critical for that particular medium.
