Aray 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

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

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

now if light ray bend towards the normal then

so second medium must be optical denser

otherwise if light ray is bending away from the normal then

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
