Question

When a light ray moves from a less dense medium into a denser medium, the light ray is refracted towardaway fromparallel to the normal.

Answer 1

Answer: its toward

Explanation:i just took assignment

Answer 2

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
