Physics Form Five: Chapter 4 - Experiment on Cathode Ray Properties

This video is very useful especially for those students who do not have a chance to do experiment in school laboratory. Inside this video shows:

• how cathode ray travels in a straight line
• how a green shadow of Maltese cross formed.
• how kinetic energy of electrons convert to light energy.
• how magnetic field deflects cathode ray. (use Left Hand Fleming Rule to determine the direction of force)
• how increasing voltages affect current and number of electrons emitted.

Enjoy and appreciate this demonstrations!
