由声现象带来的奇妙世界,使我们小组对物理这一学科产生浓厚的兴趣。课上的一些小实验,使我还觉得不够尽兴。于是,在课余时间,我们小组的同学自己做了些小实验,下面就和大家分享一下吧。一、液体传声在讲声在液体中传播时,老师举了生活中的实例。比如,钓鱼时,岸上有人说话就会把鱼吓跑;还有,在水里敲石头我们能听到声音等。不过,我们研究后认为,这个实验可用气球完成。 The marvelous world brought by the sound phenomenon has given our group a strong interest in the discipline of physics. Some small lessons in class, so I still feel enough fun. So, in my spare time, my group of classmates did some small experiments, let's share with you. First, the liquid sound in talking about the spread in the liquid, the teacher cited examples of life. For example, when fishing, people on the shore can scare the fish when they talk; and you can hear voices by knocking stones in the water. However, our study concluded that this experiment can be completed with a balloon.
