Условие: Если направить поток воздуха на вращающийся диск с отверстиями, можно услышать звук. Объясните это явление и исследуйте, как характеристики звука зависят от существенных параметров. Описание видео: Simple siren disc demonstration //. Homemade Science with Bruce Yeany Here is a simplified version of the Seebeck siren disc that has been a classic physics demonstration showing the relationship between frequency and pitch. The siren disc has a long history is sound studies and was first introduced by Thomas Seebeck in 1841 as a method of generating pure tones. It continues to be a staple of high school and college physics classes as it visually demonstrates the production of sound by interrupting the air flow through a series of holes located on a spinning disc. 3 additional notes. gained from the comments Thomas Seebeck died in 1831. August Seebeck made the tone disk. Safety first, I should be wearing safety glasses, especially being near the spinning surface wi
