A Simple Method to Measure the Angular Speed of a Spinning Object
Physics Teacher Volume 46, Number 2, ISSN 0031-921X
The angular speed of a spinning object is commonly measured using a stroboscope or a mechanically or optically coupled tachometer. We present here an alternate, simple, and instructive method to measure it using a microphone and a computer.
