Description
This programme demonstrates two famous paradoxes in physics - is light waves or particles and are electrons waves or particles? The discussion of these paradoxes is set against the debate on what i...s truth i.e. is truth objective? or is all truth subjective in the sense that it must filter via an experiment through an observer. To test the wave theory of light, Russell Stannard uses a double slit experiment and shows interference phenomenon. He also demonstrates the gold leaf experiment and uses animated film to illustrate Einstein's explanation of these results in terms of the particle theory of light.
