Observation of sound vibrations. Physics.

The simplest mechanical oscilloscope for visualizing sound vibrations Mechanical vibration. Sound. Tuning fork oscillations are harmonic oscillations. At a certain angular speed of rotation of the mirrors, we see a sine wave on the screen. In this experiment, we can see the vibrations of the tuning fork. The simplest mechanical oscilloscope. An old experiment time of the USSR. Soviet physics laboratory in the home interpretation. If you need theoretical notes on physics and engineering, then follow me on
