rktpro Posted July 2, 2014 Share Posted July 2, 2014 Have you done the experiment or read somewhere that the tube glows? You can get direct answer with a little google search, though. You should always try that first. You can also look into your book and investigate. Link to comment Share on other sites More sharing options...
