Figure below shows a version of Young’s Experiment performed by directing a beam of electrons on a double slit. The screen reveals a pattern of bright and dark fringes similar to an interference pattern produced when a beam of light is used.
1. Which property of electron is revealed in this observation.
2. If the electrons are accelerated by a p.d. of 54 v, what is the value of wavelength associated with electrons.
3. In similar experiment, if the electron beam is re-placed by bullets red from a gun, no interference pattern is observed. Give reason.
