In total internal reflection, the light travel from

rarer to denser medium and it occurs with no loss of intensity
denser to rarer medium and it occurs with no loss of intensity
rarer to denser medium and it occurs with loss of intensity
denser to rarer medium and it occurs with loss of intensity

Correct Answer: 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.
