Question

Which phenomenon causes an object to appear bent from above the surface of one medium to below the surface of another medium? A) diffraction B) dispersion C) reflection D) refraction

Answer 1

Answer: D

Explanation

Refraction is the phenomenon that causes an object to appear bent from above the surface of one medium to below the surface of another medium.

Answer 2

Option (D)

Step-by-step explanation:

Refraction is defined as the phenomenon where the light changes its course of path while travelling from one type of medium to another. This also affects the speed of the light. This process results in the formation of images by the human eyes and lenses.

This process appears to be bending of light. When a light passes from a lighter to a denser medium, it gets bend towards the normal. And when the light passes from a denser to a lighter medium then it gets bend away from the normal.

Thus, the correct answer is option (D).
