例1鼓的声音传得很远，这是由于（）．A．音调高11．振幅大C．频率低！）、音色好错解大部分同学拿到此题后认为应选B，其理由是：振动物体的l们度取决于物体的振幅，物体的振幅越大，其响度也越大，因而它传播的距离也越远．解析从理论上分析，选B似乎没有错，可是此结论与实 The sound of the drum in Example 1 was transmitted very far. This is due to (). A. The tone is high 11. Large amplitude C. Low frequency! ), sound good and wrong solution Most students get this question and think that should choose B, the reason is: the degree of vibration of the object depends on the amplitude of the object, the greater the object’s amplitude, the greater the loudness, and thus it spread The farther away the distance. From the theoretical analysis, it seems that there is nothing wrong with choosing B, but this conclusion and reality
