Question

which statement best explains the path light takes as it travels?
light moves in a straight line except at surfaces between different transparent materials, where its path bends.
light takes a curved path through matter and takes a straight path through space.
light curves to spread out through openings and move around barriers.

Explanation:

Light travels in straight lines (rectilinear propagation) in a uniform medium. When it passes between different transparent materials (like air to water), refraction occurs, bending its path. The other options are incorrect: light does not follow a curved path through matter, and diffraction (spreading around barriers) is a secondary effect, not the primary path behavior.

Answer:

Light moves in a straight line except at surfaces between different transparent materials, where its path bends.
