Final answer:
When light goes from one material into another material with a higher index of refraction, it undergoes refraction and changes its path by bending towards the normal.
Step-by-step explanation:
When light goes from one material into another material with a higher index of refraction, it undergoes refraction and changes its path.
The angle between the ray of light and the normal (a line perpendicular to the surfaces of the two materials) is greater in the medium with the higher refractive index.
As a result, the light ray bends towards the normal when entering the medium with the higher refractive index.
