Ok, it seems I haven't learned this yet. But how is this related to the period?
It is not that I do not know the definition of period, it is because I know it that I am asking about it. I am tryin to visualise the definition, .lntz said:this relates to wavelength.
i don't know if anyone has made the point yet that time period is = 1/frequency.
that is what the time period is. so your questions about how can 1 wave be completed in the same time period as all the other parts of the string, seems strange. unless your frequency is changing, the time period is constant.
sophiecentaur said:Does the definition need to go further than saying that the period is the time for one cycle to be completed at any fixed point in space?
Likewise, the wavelength is the space between identical points on the wave at a given time.
You can't get much more succinct than that.
Celluhh said:Yeah, why any fixed point, they don't even receive energy and start moving at the same time, do they have the same speed?
Here is a youtube video of a traveling wave on a long rope:Celluhh said:Uh I don't think you understand my question. Precisely because I understand how displacement of particles at different points of the wave is different, which is why the wave is formed in the first place, that I am wondering why, when the wave travels, or more specifically, energy is transferred from one particle to the next and the particles start moving consecutively, that they actually manage to all complete one
Oscillation in the same period to form one complete wave in that one period. Unless of course they are all moving at different speeds, or they all start moving at the same time, which is impossible.

Every segment of the rope is oscillating up and down at the same frequency (and the same period), but each adjoining segment has a slightly different phase, so the wave appears to be traveling.
Celluhh said:So it just happens that the time taken for one wave to be completed and one particle to
Complete its oscillation is the same ?
