Not quite something, not quite anything either, the particle is so small that it is sometimes said that it doesn’t even have a size.

It also has wave properties. The wave is not tangible like the sound waves or the sea waves, it represents it’s probability of presence in the space. This paradoxical behaviour is known as the wave-particle duality.

The wandering particle is free to move in all directions.

The particle can’t be represented. It is generally studied through its interactions rather than by itself.






The waves add up and then






separate without deformation.
