| Abstract: | This article is to describe the principles and methods of how to use the computer to assist in measuring the liquid viscosity coefficient with a self-made photo gate.Blocking optical light path,the ball makes the photodiode generate an electrical pulse.The pulse,which can measure the ball falling time and increase accuracy of the experiment,can be captured by the audition with the sound card of computer. |
