Final answer:
Light traveling from water into a material with the same index of refraction will continue in a straight path without changing direction.
Explanation:
When light travels from water into a material with the same index of refraction as water, it will continue in a straight path without changing direction.
Refraction occurs when there is a change in the medium's refractive index. If the index of refraction of the material is the same as water, there is no bending of light rays at the boundary.
This scenario exemplifies total internal reflection and illustrates how the angle at which light bends depends on the difference in refractive indices between materials.
