人教版普通高中课程标准实验教科书“电磁波的发射与接收”一节,介绍了“电磁波的发射和接收”过程.教材在“做一做”栏目里还介绍了“制作简易无线话筒”的实验.做好“电磁波”实验,有利于学生对电磁波的理解,有助于学生对物理理论知识和实践知识的双重掌握,清楚地认识到物理对如今科学技术甚至经济、文化发展的深远影响.因此,本文以电磁波的发射与接收实验现象及原理分析为研究课题,系统地进行阐述和研究. PEP general high school curriculum standard experimental textbook “Emission and reception of electromagnetic waves ” section, introduced the Make a simple wireless microphone Good “electromagnetic wave ” experiment, is conducive to students’ understanding of electromagnetic waves, help students to double the theoretical knowledge of physics and practical knowledge, a clear understanding of the physical science and technology nowadays Even economic and cultural development of the far-reaching impact.Therefore, this article launches and receives the electromagnetic wave phenomenon and the principle analysis as the research topic, systematically carries on the elaboration and the research.
