When a ray pass through a denser medium to rarer medium the TIR can occur.
It is also is when the incident angle is greater than sin-1(1/n)  here n= refractive index

Total internal reflection, in physics, completereflection 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.
