在初中物理光现象学习中,凸透镜成像是重点,更是难点。特别是在新课程的实施过程中,更加重视物理与生活的联系,对于刚刚接触物理的初中生来说,成像规律的掌握及实际应用都有一定的难度。在多年的实践中,将凸透镜成像的规律合为一图,在帮助同学们巩固和掌握凸透镜成像规律及 In the learning of physical light phenomenon in junior high school, convex lens imaging is the key point, and it is more difficult. Especially in the implementation of the new curriculum, more attention is paid to the connection between physics and life. For junior students who have just come into contact with physics, the mastery of imaging laws and practical applications have certain difficulties. In many years of practice, the laws of convex lens imaging have been combined into one graph to help students consolidate and master the imaging law of convex lenses.
