摘要
波粒二象性是量子力学中最重要、最根本的概念之一,但对于光既是波又是粒子,且随着观测手段不同而分别观察到波动性或粒子性这点在高中物理课程中讲解得比较抽象,学生一般都难以理解和消化。本文通过从对光本性研究的历史出发,详细介绍光的波动说和微粒说世纪之争。通过物理科学发展的历史为出发点和主要线索,跟随大争论年代诸多著名物理学家的脚步,引导学生深入认识和理解光的波动性和粒子性两个方面,进而统一到光的波粒二象性的概念。从光的本性的教学中让学生能体验探索自然规律的艰辛与喜悦,树立研究过程中不畏权威、坚持不懈的精神,进而发现物理规律中丰富的人文内涵。
Wave-particle dualism is one of the most importantand fundamental concepts in the quantum mechanics. However,sometime light is a wave, and sometime it＇sa particle, which de-pends on the observation method. This kind of abstract interpre-tation makes it hard for students to understand and know the na-ture of light well. Herein, in this paper, starting from the researchhistory of the nature of light, the debating between wave theoryand corpuscular theory has been introduced with detail. With thehistory of the physics science development as the starting pointand the main clues, following the footsteps of many famousphysicists in the big debate, the students will be guided to deepknow and understanding the wave and particle properties for theboth sides of light, and then finally unified to the concept of wave-particle dualism for the nature of light. Through the teach-ing and studying on the nature of light, the students could feel thedifficulty and joyful for the exploring of the laws of nature, build-ing the spirit of no fear to authority and perseverance, and furtherto discover the abundant humanistic connotation in the laws ofphysics.
