T.i.r

when we increase the value of refractive index of the prism n2 > n1
surely the light may fall at angle greater than critical angle i have a doubt that if we do so the value of critical angle of the prism may change and the light may not undergo total internal reflection and even may refract then why we consider that it undergo T.I.R
