Classical Particles
Classical particles are emitted at the source and arrive at the detector only if each particle passes through one of the slits.
Key features:
- Particles arrive “in lumps”, i. e. the energy deposited at the detector is not continuous, but discrete. The number of particles arriving per second can be counted.
- The number which arrive per second at a particular point (x) with both slits open (N12) is just the sum of the number which arrive per second when only the top slit is opened (N1) and the number which arrive per second when only the bottom slit is opened (N2).
