# Particle property of electron ?? watch

1. Electrons, like light, have both wave and particle properties. You can demonstrate its wave property by the diffraction experiment, but what argument are you gonna provide to show that electrons have particle properties too ??
2. What happens when electrons are diffracted? ?
3. Count from Geiger Muller tube according to the arrival of one electron
4. i think you can use the photoelectric effect, because electrons can be displaced by a photon

you can also use the fact that electrons can be accelerated in electric fields
5. electons interact with matter for example a phosphor screen flashes of light, they have mass, have a charge, they may be deflected by electric fields, deflected by a magnetic field, and you can use F=ma
6. electrons diffract through a crystal to give a circular fringe patten, also the individual detection of beta particles by the GM tube indicates the particle property.

the 'fringe pattern' is the pattern where the electrons are most likely to b found rite?
they cant b split themselves...
8. this is evidence for a wave, if you try to justify that the elecron is a particle with a probability then that is valid but not asked for by the exam board, and also offers no reason why the particles have probabilities, unlike the wave model.

the fringe patters is where the electrons are found, by a screen that can visibly show areas of high intensity (intensity meaning electrons per second, not energy per unit area)
9. yup got it, thanx
10. btw..we r talking about a stream of electrons here
what if its a single electron that goes through the slit?
probably a silly approach, but still wondering what it would do to that single electron!
11. it's not on the syllabus, but the electrons fired singly would still produce the pattern over a long enough time period. this is when the wave theory fails, because the electron "wave" simply cannot undergo interference when it's constituents, electrons, are fired seperately.

its like the electron has a probability to land on those places. if youre interested, buy "QED" by Feynmann, it describes it very well.

12. thats wat i thought
