Summary[edit]
| Description |
Македонски: Низ шупелка се пропушта водород од балон (како на поставката). Најпрвин, низ шупелката поминува воздухот присутен во шишето и предизвикува осцилации на столбот од гас во шупелката. Се генерира тон со определена честота. Потоа, воздухот постепено се заменува со водород, при што се генерира тон со променлива, растечка честота. Честотата на тонот се покачува за речиси две октави. Имено, ефективната маса на осцилаторот (столбот гас во шупелката) континуирано се намалува за околу 14,5 пати на крајот, па честотата се зголемува за речиси четири пати (3,8 пати поточно). Осмислено и изведено од Марина Стојановска, Миха Буклески и Владимир Петрушевски, Институт за хемија, ПМФ, УКИМ, Скопје.
English: A stream of hydrogen is passed through a recorder (cf. the experimental set-up). At first it is the air present in the bottle that oscillates and gives a tone with some frequency. After a while, the air being continuously replaced by hydrogen, the tone’s frequency increases. The frequency increases by almost two octaves. Namely, the effective mass of the oscillator (the gas in the recorder) continuously decreases by a factor of 14.5 in the end, so the frequency increases almost 4 times (3.8 to be precise). Planned and performed by Marina Stojanovska, Miha Bukleski and Vladimir Petruševski, Department of Chemistry, FNSM, Ss. Cyril and Methodius University, Skopje, Macedonia. |
