Question

use the information and images to answer the following question. group x develops a model of refraction during class. the group constructs a short description to define refraction underneath their model. group y develops a model based on their data. group xs model group ys model group xs original description:
efraction occurs when light enters a new medium and it bends to change direction.\ both models are correct. how can group x include information from group ys model to best revise their original description? refraction occurs when light enters a new medium at an angle and it bends to change direction. refraction occurs when light enters a new medium and it bends to change direction before returning to its original direction. refraction occurs when light enters a new medium and is blocked by the medium. refraction occurs when light enters a new medium and it changes speed but not direction.

Explanation:

Group Y's model shows light entering the medium perpendicularly without bending. Group X's original description can be improved by noting that refraction occurs when light enters a new medium at an angle and bends. When light enters perpendicularly (as in Group Y's model), there is no bending.

Answer:

Refraction occurs when light enters a new medium at an angle and it bends to change direction.
