No light pases into the rarer medium but the entire light is reflected back into the denser medium . This is called tir

When a light ray is traveling from denser medium to rarer medium and made to incident on the separation between two media at an angle greater than critical angle of the medium then the light ray is reflected back into the same denser medium...This is called TIR...
CONDITIONS....
• Light ray must travel from denser medium to rarer medium...
• Angle of incidence in the denser medium must be greater than critical angle of the medium....

Total internal reflection, in physics, complete reflection of a ray of light within a medium such as water or glass from the surrounding surfaces back into the medium. The phenomenon occurs if the angle of incidence is greater than a certain limiting angle, called the critical angle

Total internal reflection, in physics, complete reflection of a ray of light within a medium such as water or glass from the surrounding surfaces back into the medium. The phenomenon occurs if the angle of incidence is greater than a certain limiting angle, called the critical angle. In 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 medium at an angle of incidence greater than the critical angle. For a water-air surface the critical angle is 48.5°. Because indices of refraction depend on wavelength, the critical angle (and hence the angle of total internal reflection) will vary slightly with wavelength and, therefore, with colour. At all angles less than the critical angle, both refraction and reflection occur in varying proportions.
