Answer 2

8.) 42° is right movingg from rarer to denser medium the light ray bends towards the normal

9.) I think refractive index is req to calculate the angle of refraction.....angle of emergence = angle of refraction.

10.) as the angle of incidence increases it may occur for higher values of incident angle the the refracted Ray may emerge out of some other face
