Question

A ray diagram shows the ray passing from medium 1 to medium 2. After passing into medium 2, the ray bends away from the normal.

What does this ray diagram illustrate?

reflection with scattering in a medium
reflection without scattering in a medium
refraction with medium 1 denser than medium 2
refraction with medium 1 less dense than medium 2

Answer 1

C. refraction with medium 1 denser than medium 2

Step-by-step explanation:

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 light ray bend towards the normal then

`\mu_2 > \mu_1`

so second medium must be optical denser

otherwise if light ray is bending away from the normal then

`\mu_2 < \mu_1`

so second medium is rarer than first medium

so for the given condition of the question correct answer will be

refraction with medium 1 denser than medium 2
