Refraction, or bending, of light rays as they move from one material to another occurs because light waves - A: travel the same speed through all types of materials
B: travel at different speeds through different materials
C: are interrupted by sound waves as they travel
D: are compressed as they speed up

A: travel the same speed through all types of materials

Explanation:

Light refracts whenever it travels at an angle into a substance with a different refractive index (optical density). This change of direction is caused by a change in speed. ... When light enters a more dense substance (higher refractive index), it 'bends' more towards the normal line.

Light travels the same speed.

that is probably false!
