Hi all new here so be gentle,
We do an experiment in one of our labs that has a lot of error introduced by the students who must time a steel ball dropping in various solutions in glass tubes of various diameters. To eliminate this error we would like to create some electronic detection system that would detect the ball as it crosses a point (just after it has been release so it attains max velocity) and just before it reaches the end of the tube. We have been racking our brains trying to come up with an approach we have a few ideas but nothing that looks really promising. I would appreciate any help we could get in this matter, or ideas to pursue to achieve this.
Thanks,
Ed
