METHOD AND DEVICE FOR STUDYING LONGITUDINAL STANDING WAVES IN SOLIDS

摘要

the invention refers to a method and a device for stationary wave longitudinal study in solid, used as teaching material in the process of education.the method provides for getting systems where stationary longitudinal and direct observation, with the naked eye.of the maximum (ventrelor) and minima (nodes) of the end turns of a flat elastic oscillation excited periodically vertically and spring at one end, for the first ten...12 harmonics, and the device is composed of an elastic spring, lying on a shelf support, from a speaker provided with a rod that connects between the membrane diffuser and resortand a audiofrecventa generator.
