D) frequency.

Question

Quizplus · Accepted Answer

Reflection, refraction and diffraction all cause light to change its direction. Reflection is the bouncing back of light when it strikes the surface of an object, refraction is the bending of light as it passes through a medium, and diffraction is the spreading out of waves as they encounter an obstacle or opening. While these phenomena may affect the intensity or color of light, the primary change is in its direction. The frequency of light remains constant unless it interacts with matter in a way that alters its energy.
