According to the Copenhagen interpretation, physical systems generally do not have definite properties prior to being measured,No. That is a misleading formulation. It is true that we don't know anything about a particle until it interacts with another particle. The fact that I don't know whether you are wearing a hat until I see you, has nothing to do with whether you are or are not wearng a hat: I can't draw an accurate picture of you until we have met, but that meeting doesn't determine your appearance because you must have put the hat on

*before*we met.

and quantum mechanics can only predict the probabilities that measurements will produce certain results.Yes

The act of measurement affects the system,Yes

causing the set of probabilities to reduce to only one of the possible values immediately after the measurement. This feature is known as wavefunction collapse.No. What happened is what you measured. Waveform collapse is a

*mathematical model*of what happens.
