          Answer & Explanation
         Answer: B) denser to rarer medium and it occurs with no loss of intensity         
         
Explanation: According to wave theories, for Total internal reflection tohappen: Light must travel from denser medium to rarer medium. Angle of incidence should be greater than critical angle. As in case of TIR, the image is perfectly clear, it implies that there has been no loss of intensity.
