| Popis: | There are many resonanse phenomena in nature which are very familiar. They show the characteristic of waves. Thus the resonance phenomena in air columns and in stretched strings are often taught in generel physics courses. But we can not find any reason why resonance phenomena are happened for some proper lengthes of the air columns or the stretched strings in texbooks. Thus in order to answer this problem the wave motions in the tubes or in the strings are represented to be a superpoosition of all waves reflected at both ends. Equations for the air columns of 5 different bondary conditions and the stretched strings are obtained which lead the standing waves having the maximum amplitudes for the proper lengthes as resonance. |
