The Chinese word 反射 (fǎnshè), meaning "reflection", is a compound formed by combining two meaningful characters: 反 (fǎn), which conveys the idea of "reverse", "opposite", or "against", and 射 (shè), which means "to shoot", "to emit", or "to project". Together, they create a logical semantic unit describing the action where something (like light or sound) is projected or emitted and then bounces back in the opposite direction, literally, a "reverse shooting". This formation follows the common Chinese morphological pattern where two characters with related meanings are combined to precisely define a specific concept, in this case, a fundamental principle in physics.
