一日,一地理同行拿着一本普通高中课程标准实验教科书《地理》(选修2),冲入物理办公室,面带笑容地说:“请教个问题,海啸波到达浅海后,为什么波长变短,波峰变高”.对于海啸波,虽然属于机械波,但笔者之前几乎从未对它认真研究过.所以,笔者查阅了大量资料,最终,不仅给这个地理同行一个较满意的答复,对于海啸波中的几个问题进行归纳和思考分析,并撰写成文,以与大家探讨.还对于这个能量大、波及范围广、杀伤力破
On the 1st, a geography colleague holds an ordinary high school curriculum standard experimental textbook “Geography” (Elective 2) into the physical office with a smile: “Ask a question, why did the wave length change after the tsunami wave reached the shallow sea Short, high peaks. ”For the tsunami wave, although it belongs to the mechanical wave, but the author has never seriously studied it before .So, I access to a large amount of information, and ultimately, not only to the geography counterparts a more satisfactory answer to Tsunami wave of several issues summarized and thinking analysis, and writing written, to discuss with you.
