Werner Weisenberg ?
From question #18 of Achieve, can anyone explain this equation and what we use it for ?

Re: Werner Weisenberg ?
I discussed it in detail in class, example, calculation, etc.
Fortunately I organized my lectures are recorded for students to watch.

Re: Werner Weisenberg ?
This is the uncertainty principle, it basically says that if you know the specific position of an electron (or other particle?), then you will have a greater uncertainty for the momentum of this particle, and vice versa. So if you have a small delta x (small uncertainty of position), then you will have a larger delta p (large uncertainty of momentum). If you know the uncertainty in position or momentum of the particle, you're able to use this principle to solve for the other uncertainty.
The m and delta v comes from the fact that p=mv, if you use uncertainty of position (delta p) you will get the uncertainty of velocity (delta v).

The equation looks more daunting than the other ones we were given and the reasoning and calculations with it are definitely on the advanced side. This problem is a straight-shot in the calculator and you're given everything you need to find the uncertainty in position. h and 4pi are constants, and don't move at all, but the uncertainty in position and velocity do. Since we're looking for uncertainty in position, the form of the equation we need is. Δx = h/(4pi*Δp). Δp is created by multiplying Δv and mass together. Both those two numbers are given. The equation to solve for Δx is Δx = h/(4pi*m*Δv) which is in your attachment. That goes into your calculator and you sub out all the letters for the right numbers and put in the uncertainty in velocity you are given in the problem.

Re: Werner Weisenberg ?
This is for uncertainty of a position. It is derived from two different formulas on the equation sheet.
