- - - - Distributions of the electrons on the screen are smooth
        
        sum of these distributions are smooth
        
        A bell-shaped curve
    - - Interference pattern appeared :open_mouth:
      - How could this interference happen? :thinking_face:
        Electron cannot be split, right ? :thinking_face:
        How can it appear to go through both slits at once? :thinking_face:
      - An experiment was carried out to find out which slit actually the electron went. :+1::skin-tone-2:
        
        place a strong light source behind the wall
        
        place Geiger counters all over the screen so that whenever an electron reaches the screen we hear a click on the counter
        
        when an electron passes through either of the slits,
        on its way to the counter, the light will scatter to our eyes. (electric charge produce light)
        
        Result: suddenly, the interference dissappeared! :!:
        BUT, when turn off the light, the interference appeared again :!!:
- - - - Can determine the phase shift between the wave functions and not its individual phase shift separately
      - Resulting from phase shift between
      - Representing interference pattern
      - :pencil2:The terms with asterisks represent the interference pattern results from phase shift
- - - - Physical experimental examples featuring this include: Blackbody radiation, photoelectric effect, pair production, compton effect, double slit experiments...
  - - - The same material particle is described by both its wave and particle picture.
        
        The wave function is used and it describes simultaneously the wave and particle behavior of microscopic systems.
        
        A quantum system is neither a pure particle nor a pure wave but actually both hence the complementarity principle introduced by Bohr.
      - The measurement of the Quantum state properties gives only one property, meaning the wave property or particle property not both.
        
        In Quantum mechanics, the aspects of particle and wave manifest only when subjected to and any measurement will destroy the initial quantum state information and give only one property information, either that of a particle or a wave.
