1Sound obeys reflection rules just like light, and reflected sound is used in echo and acoustic design.
2The reflection of sound follows the same laws as light reflection: angle of incidence equals angle of reflection. This principle is crucial for understanding how echoes and reverberation occur. Questions on this topic often involve calculating distances using echo times or explaining differences between echoes and reverberation. Common mistakes include forgetting to divide the total distance by two when calculating the actual distance in an echo problem.
3Reflection of Sound should be revised by linking the physical idea, the formula or diagram cue, and the final result.
4Keep the physical observation and the reason separate, then connect them clearly.
