Kayla drew two ray diagrams to compare the behavior of light rays.
what do the diagrams illustrate?
a.) diagram x shows reflection, and diagram y shows refraction from a less dense to a denser medium.
b.) diagram x shows refraction from a less dense to a denser medium, and diagram y shows reflection.
c.) diagram x shows reflection, and diagram y shows refraction from a denser to a less dense medium.
d.) diagram x shows refraction from a denser to a less dense medium, and diagram y shows reflection.

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.

if the thermos has a vacuum innner, then heat through conv currents and conduction are reduced = vacuum flask

explanation:

v=uf/(u-f)

= 5.-10/(5+10) convex lens has negative focal length
