Answer 2

let us consider the medium outside the prism to be air

now we know that the light bends towards the normal when it travels from rarer to denser medium here in this question the rarer medium is air and denser medium is prism

so just draw a normal on the surface on which the Ray is incident and bend it towards the normal

remember the normal is always drawn perpendicular to the surface on which the ray is incedent

for eg pls refer the attachment
