Particle properties of radiation
... For the case of a particle we can locate its location and momentum precisely But how do we ‘locate’ a wave? Wave spreads out in a region of space and is not located in any specific point in space like the case of a particle To be more precise we says that a plain wave exists within some region in sp ...

Quantization of Mechanical Motion
... Wave Function Since a measurement on a given quantum object has no deterministic result, the only way to describe it is to introduce the probability to find a specific value of a physical variable in a large set of results of identical measurements. This information is addressed by the introduction ...
