falls normally on the surface of
another medium. While entering the

A) goes straight into the second medium
without bending

d)does not enter the second medium at all
choose the correct option
Answers
Answer:
Answer is
Explanation:
When light rays traveling from one medium fall at the surface of another medium part of the light rays returns back to the same medium.
For example in window mirror we can see our image and we can also see outside objects because of both reflection and refraction of light.
Refraction is the bending of light rays after entering a medium where its speed is different. Due to refraction of light, when a ray of light passes from a rarer medium to a denser medium, bends towards the normal to the boundary between the two media. The amount of bending depends on the indices of refraction of the two media. Hence, when a ray of light from air enters a denser medium, it bends towards the normal.
