Answer:
D.) Diagram X shows refraction from a denser to a less dense medium, and diagram Y shows reflection.
Explanation:
As per ray diagram we can see that light ray moves from one medium to another medium
So this must be the phenomenon of refraction of light
Now in this phenomenon of light we can see that initially light makes small angle with the normal
After moving into the other medium the light makes more angle with the normal
so here light is bending away from the normal when it is moving into the other medium
So here light is moving into less denser medium from denser medium
So correct answer must be
D.) Diagram X shows refraction from a denser to a less dense medium, and diagram Y shows reflection.
