Reflection in wave theory involves the bouncing back of waves when they encounter a surface, as explained by Huygens' principle. Wavelets, as a second generation of waves, emerge from the primary wave front and are essential in understanding complex wave behaviors. The discussion highlights the relationship between wavelets and the reflection of plane waves on plane surfaces. Clarification is sought on how wavelets relate to the broader concept of wave reflection. Understanding these concepts is crucial for grasping the principles of wave behavior in various contexts.
