Could someone help me with the path taken by the emergent ray for blue light if it is refracted most than red light rays.the emergent ray for the red light lies on the boundary of the prism after being diffracted and forms the criticle angle(c). Is the path taken by the refracted blue light ray going to towards the normal,away or theres going to be total internal refraction?

Its angle of incidence is too large for it to pass through that face.

Note that the refractive index itself, and hence the critical angle for blue, depends on the wavelength of blue light.

Diffraction of blue and red light on a prism

May I suggest that the term 'diffraction' in the title of the post be changed to 'refraction'.
