Step 1: Analyze the definition provided. The question describes a phenomenon where a wave changes direction as it moves from one medium to another, and this change in direction is caused by a shift in its speed. Step 2: Evaluate the given options. A. Refraction: This is the bending of a wave as it passes from one medium to another, which occurs because the wave's speed changes in the new medium. This definition perfectly matches the description in the question. B. Dispersion: This refers to the separation of a wave into its component frequencies (e.g., white light into a spectrum) due to the dependence of the wave's speed on its frequency in a given medium. While it involves speed changes, it's not the primary term for the general change in direction between media. C. Reflection: This is the phenomenon where a wave bounces off a surface and returns into the same medium. It does not involve passing into a new medium. D. Diffraction: This is the bending of waves around obstacles or through an opening. It does not primarily involve passing from one medium to another due to a change in speed. Step 3: Conclude the correct answer. Based on the definitions, Refraction is the term that describes a wave changing direction as it passes from one medium to another due to a shift in its speed. The correct answer is A. A. Refraction What's next?
