If a ray passing from one medium to other medium then it will refract either away from normal or towards the normal

This all we can find out using snell's law

$\mu_1sin\theta_1 = \mu_2sin\theta_2$

now if we wish to find the angle inside other medium then we will have

$sin\theta_2 = (\mu_1)/(\mu_2) sin\theta_1$

now if second medium is given optical denser

so we will have

$\mu_2 > \mu_1$

so here we will have

$\theta_2 < \theta_1$

so here we can say that ray will bend toward the normal as angle is decreased here
